I am having some headache in my top of back side and sometimes both left and right side(back area) of my head. I am also feeling pain in my back leg and knee joints. No runny nose but blocking little bit sometimes. Eyes are burning mostly at evening and feeling sleepy. A small temp(98.9 - 99 f) is coming mostly at evening. Small water color cough(sometimes dry). feeling small dizzy after some work.. Feeling little heavyness in head. Sometimes a small chest pain(might be due to gastric). A small breath problem (mostly at evening). Also feeling a smll dizzy at the time of back head pain. The headache is not painful but I am fearing for this. I don't know whether I have to consult any doctor or not. The headache is from 1 month but feeling sometimes only.but cold symptoms are from 4 days. I am feeling a small uncomfortable in breath and small dizzy in bus travel. I have also some gastric and acidity problem. Is there any disease I have. I just want to get rid from this fear.
