Hello, I empathise with your concerns. Three issues to be addressed : 1. Recurrent colds Do you have a history of asthma or allergies? This could predispose you to get frequent cough and viral infections. If you recoughing atleast 20 days out of 60 days, with cough disturbing sleep, it is likely that you have asthma. Inhaled steroids like fluticasone and relievers like salbutamol will greatly help (and you can use them at home) 2. Abscess in armpits - It is likely that you have a bacteria called MRSA on your skin that increase the frequency of abscesses. Treatment would be to apply mupirocin ointment on your nostrils, armpits twice a day for 5 days and wash well (especially armpits and groin) with.chlorhexidine body wash. 3. Tiredness Please check your hemoglobin, vitamin D levels.and thyroid function if not already done. If you re having chronic pain and tiredness, it is also.a symptom of infectious mononucleosis. A simple blood test for EBV VCA antigen will.diagnose this. Hope this helps and feel better soon!
