“Heat in my body.” “My heart is cutting.” “Pepper in my head.” These are not vague complaints. They are how anxiety is actually described here.
Anxiety produces genuine physical symptoms — chest tightness, palpitations, heat, headaches, stomach trouble, body pain — through the fight-or-flight response. In Nigeria these are frequently the only symptoms someone reports, which means anxiety here is routinely treated as malaria, typhoid, ulcer, hypertension or a spiritual problem before anyone asks about worry.
Get checked first
This has to come before anything else.
Chest pain, breathlessness, palpitations and persistent headaches all have serious medical causes. If you have not been assessed by a doctor, be assessed. Do not read this article and decide your chest pain is anxiety.
The picture this piece describes is the one that emerges after proper investigation: repeated tests, nothing found, symptoms continuing, and no one thinking to ask what else is going on in your life.
Why the body speaks first
There is a tendency to treat physical expressions of distress as a lesser or confused version of the real thing. That is wrong, and it is worth saying plainly.
Anxiety is a whole-body response. Adrenaline and cortisol raise your heart rate, tense your muscles, redirect blood away from the gut, speed up your breathing and sharpen your senses. Every one of those has a physical consequence you can feel. The physical symptoms are anxiety, not a mask for it.
What varies between cultures is which part people notice and report. In settings where emotional vocabulary is used freely, people say they feel anxious. In settings where distress is more readily expressed through the body — which includes much of Nigeria — people report heat, pressure, pain. Same condition, different presenting complaint.
The phrases carry real clinical information:
- “Heat in my body” — a spreading warmth or burning, often in the chest, head or limbs
- “My heart is cutting” — palpitations, skipped beats, a lurch in the chest
- “Pepper in my head” — burning or crawling head sensations
- “Something is moving in my body” — internal tremor, crawling sensations
- “My body is weak” — the exhaustion that follows sustained arousal
- “Pressure in my head” — tension headache
None of these are metaphors people invented. They are descriptions of sensations that are actually happening.

The full physical range
Chest and heart: tightness, pain, palpitations, awareness of your own heartbeat.
Breathing: shortness of breath, feeling unable to get a full breath, sighing repeatedly, a lump in the throat.
Head: tension headache, dizziness, light-headedness, pressure, burning sensations.
Gut: nausea, appetite loss, churning, urgency, constipation, symptoms often labelled ulcer or IBS.
Muscles: jaw clenching, neck and shoulder pain, back pain, tremor, twitching.
Skin and temperature: sweating, hot flushes, cold hands, tingling in fingers and around the mouth.
General: exhaustion that sleep does not fix, poor concentration, disturbed sleep.
Tingling and dizziness deserve a note, because they frighten people most. They are usually produced by over-breathing — anxious breathing shifts blood chemistry, which causes exactly those sensations. Harmless, extremely unpleasant, and easily mistaken for something neurological.
The road most Nigerians take
The path is remarkably consistent.
It starts with self-medication — malaria treatment, typhoid treatment, ulcer medication bought at the chemist. No improvement.

Then the clinic. Blood tests. Perhaps an ECG, perhaps a scan. Nothing conclusive. Sometimes a diagnosis of “stress” delivered in a way that sounds like dismissal.
Then a second opinion, and a third. Different labs, more money. Each clear result reassures for a few days.
Then, frequently, the spiritual route — because a body that hurts with no cause fits that explanation more neatly than an unexplained one does.
Somewhere in that sequence, months or years pass. Nobody has asked how the person is sleeping, what has changed at home, or whether they are worried about anything.
Two things make this worse. Anxiety about the symptoms produces more symptoms, so the loop tightens. And if the checking and reassurance-seeking becomes the centre of things, that is health anxiety, which is a treatable condition of its own.
If the symptoms come in sudden overwhelming waves that peak in minutes, read panic disorder — that is a specific pattern with a specific treatment.
Signs it is worth considering anxiety
Not a diagnosis, but a prompt to raise it with a clinician:
- Investigations have been done properly and repeatedly found nothing
- Symptoms move around the body, or change over time
- They worsen under stress and ease on good days or holidays
- They are worse in the morning, or when you lie down at night with nothing to distract you
- Your sleep is disturbed
- They began around a difficult period — a bereavement, job loss, a move, money trouble
- You are told you look well while feeling terrible
- You are constantly monitoring your own body
What helps
Treat the anxiety, and the body follows. This is the part people find hardest to accept, and it is consistently what works. CBT has strong evidence for anxiety presenting physically. It usually involves understanding the mechanism — knowing why your hands tingle takes a surprising amount of the fear out of it — then reducing the monitoring and checking that amplify everything.
Breathing, done properly. Over-breathing drives several of the worst symptoms. Slow breathing out for longer than in, practised daily rather than only in a crisis. Our guide to breathing techniques for stress relief covers the technique.
Cut the stimulants. Caffeine, and especially the energy drinks sold everywhere here, produce palpitations, tremor and heat directly. A fortnight without them is a genuinely useful experiment.

Sleep. Sustained sleep loss amplifies every physical symptom of anxiety. See insomnia if that is part of the picture.
Movement. Regular activity uses the adrenaline the body has prepared and has real evidence behind it for anxiety.
Stop the repeat testing, with your doctor’s agreement. Once you have been properly assessed, further scans stop being reassurance and become part of the cycle.
Say it to a doctor in their language. “I have been having chest tightness and palpitations, all my tests are clear, and I want to talk about whether anxiety could be causing this.” That sentence redirects a consultation faster than describing the symptoms again.
What not to say to someone
“It is all in your head” is both wrong and cruel. The symptoms are in their body. What is happening is that their body is responding to something their mind is carrying — which is a different statement, and a much easier one to accept.
Frequently asked questions
Can anxiety cause real physical symptoms?
Yes. The fight-or-flight response produces genuine changes in heart rate, breathing, muscle tension and digestion. The symptoms are real, not imagined.
What does “heat in the body” mean medically?
It usually describes a spreading warm or burning sensation associated with the stress response. It is a common way anxiety is described in Nigeria and it should be taken seriously as a symptom.
Why do my tests keep coming back normal?
Because the symptoms are produced by physiological arousal rather than by disease. Once serious causes are excluded, more tests tend to sustain the cycle rather than end it.
Should I ignore chest pain if I think it is anxiety?
No. Get chest pain assessed medically. Only consider anxiety once serious causes have been properly ruled out.
How is this treated?
CBT for anxiety has the strongest evidence, alongside reducing stimulants, improving sleep and stopping repeated investigations. Filter for anxiety experience in our directory.
