I'm 27 year old, I played sports alot in school & college but now I do exercise a little. My body is prone to continuous hard sneezing, running nose & cold badly from long time as weather/atmosphere changes. Then suddenly more sweating on forehead & in hair even in cool weather (even when a.c/rain on) I went to doc many times they told me that you have allergic problem & will get over after a certain age. Some says you have immunity problem. I took medicine also but no relief. I mostly face these problems when like (1) take bath in evening (this happens also when I was in college. 4 years ago) (2) sudden different/hard smell (like food making in kitchen, after bringing out of cold clothes which are packed from more than 6 month etc (3) if come in contact with dust small particles while cleaning home especially. Not felt this problem at dusty road) (4) sometimes after waking up (may be bcz sudden temp change of body) (5) sometimes after masturbation. (6) working late at laptop leads to eye pain, water from eye & then running nose starts then cold & continuous hard sneezing. What problem do I have and how can I get ride of it?
