It started on 20 July. Both of my feet got swollen with pain. I was not able to walk properly. I went to see the doctor and was told to take Tylenol and do hot water therapy . By 26 July fever also started with swing from normal to 101 F. I went to a walk-in clinic and was asked for several blood and urine test along with chest x ray. Next day I was told that the blood reports are all good with no sign of infection however the chest x ray is showing enlarged lymph nodes and therefore CT scanning should be done. Two weeks later the CT scan was done and after further two weeks I was told that lymph nodes are confirmed on one side with size as big as 4 cm. I was then sent for respiratory test. Report came good showing no restriction before or after Ventolin. It has been two months now and no diagnosis are made. My cough gets better and worse during the day. When I take Tylenol, it goes away as if it was never there. During night I do not cough. It starts after food or eating anything. It increases during afternoon if I do not take Tylenol otherwise it is okay. Fever is gone but feeling of tiredness and pain returns with cough if I do not take Tylenol. What it is?
