Feeling tired after fever
I had fever for 2 weeks. Fever is gone but white mucus still comes from cough and nose. Since then I feel constant low energy, heavy head, and eyes feel very heavy even with good night sleep. Blood tests normal. Thyroid normal. I have taken monthly Vitamin D3 (Pores D3). I sometimes get palpitations during anxiety.
Please advise cause, treatment, and if I can safely resume 8–9 hours office desk work.

The most likely explanation for your current symptoms (constant low energy, heavy head, heavy/tired eyes despite good sleep, white mucus from cough & nose) after a 2-week fever is post-viral fatigue syndrome / prolonged post-viral asthenia (very common after respiratory infections, even when blood tests are normal).
The white mucus still present means the respiratory tract inflammation has not fully settled yet — this is typical 2–6 weeks after viral illnesses (adenovirus, rhinovirus, influenza, RSV, etc.). The heavy head + eye fatigue + low energy are classic brain-fog-like features of post-viral state. Palpitations during anxiety are almost certainly anxiety-related (not primary cardiac) and are very common when the body is still recovering.
Other causes are much less likely since:
• Blood tests + thyroid = normal
• No fever now
• No major weight loss, night sweats, swollen nodes, severe shortness of breath, or neurological signs
Next Steps
1. Give your body time — most people with this exact pattern improve noticeably in 3–8 weeks after fever ends (total illness duration 5–10 weeks).
2. See a doctor (GP or internal medicine) within the next 1–2 weeks if:
• Symptoms get worse instead of better
• New fever returns
• Cough changes (yellow/green sputum, blood, severe)
• Breathing difficulty or chest pain appears
They may check:
• Repeat CRP/ESR (inflammation markers)
• Chest X-ray (if cough persists >4 weeks total)
• Possibly ferritin (even if CBC normal — low ferritin can cause fatigue)
3. Safe to resume 8–9 hours desk work?
→ Yes — but modified (not full intensity yet).
Start with 6–7 hours/day maximum for the next 1–2 weeks.
Take short breaks every 45–60 min (5–10 min walk, eye rest, stretch).
If brain fog / eye heaviness becomes severe by afternoon → reduce to 5–6 hours or work from home part-time.
Full 8–9 hours is usually realistic again in 2–4 weeks if you follow recovery steps below.
Health Tips
• Hydration & mucus clearance
• Drink 2.5–3.5 liters water/day (warm water + lemon/honey helps mucus)
• Saline nasal rinse (NeilMed or Sterimar) 2×/day
• Steam inhalation 10 min 2×/day (plain or with few drops eucalyptus oil)
• Energy & brain fog support
• Eat small frequent meals (protein + complex carbs + healthy fat every 3–4 hours) — avoids energy crashes
• Prioritize protein (eggs, chicken, fish, paneer, lentils, Greek yogurt)
• Add omega-3 (fish or 1 g EPA+DHA supplement) and magnesium glycinate 200–300 mg at night (helps fatigue, anxiety, eye strain)
• Eye & head heaviness
• Follow 20-20-20 rule (every 20 min look 20 feet away for 20 sec)
• Use artificial tears (Refresh Tears / Systane) 3–4×/day
• Limit screen brightness + blue-light filter after 6 pm
• Anxiety & palpitations
• Practice 4-7-8 breathing (inhale 4 s, hold 7 s, exhale 8 s) × 4–5 cycles when palpitations/anxiety start
• Avoid caffeine after 2 pm
• Short walks (10–15 min) 2–3×/day — improves circulation & mood
• Vitamin D
• Continue 60,000 IU monthly (or switch to daily 2,000–4,000 IU) — recheck level after 2–3 months
You are in the recovery tail-end of a viral illness — this sluggish phase is frustrating but temporary for almost everyone.
Rest smart (not complete bed rest), eat nourishing food, stay hydrated, protect sleep — symptoms usually fade steadily over the next 3–6 weeks.
If anything worsens or new symptoms appear, see a doctor promptly.
For more personalized advice (diet ideas, exact supplements, or when to push back to full work hours), feel free to consult online.
Take care — you’re already improving

Feeling tired and low in energy after a prolonged fever is very common and is usually due to post-viral fatigue syndrome. Even when blood tests and thyroid are normal, the body may take 3–6 weeks to fully recover.
The white mucus from nose and cough suggests ongoing upper respiratory tract inflammation or sinus congestion, which can cause heavy head, eye heaviness, and tiredness.
Occasional palpitations during anxiety are also common and usually not dangerous if ECG and thyroid are normal.
Next Steps
Please seek review if:
Fatigue worsens instead of improving
Palpitations increase
Breathlessness, chest pain, or recurrent fever develops
For personalized treatment and proper evaluation, you may consult me directly through a paid consultation.
Take care and wish you a speedy recovery.
Health Tips
Take adequate fluids (water, coconut water, ORS)
Start multivitamin (A to Z) once daily
Steam inhalation twice daily
Saline nasal spray if nose blockage or mucus persists
Maintain regular sleep and light physical activity
Avoid overexertion for 1–2 weeks
Regarding office work:
You may resume desk work, but start gradually —
begin with 5–6 hours daily, take short breaks, and increase to 8–9 hours over 1–2 weeks depending on energy levels.
