Its been two months since i am having low grade fever b/w 99 - 100 F and generally occure during evening along with that i am having extreem fatigue (sometimes only),wet cough with (black,green) mucus,and one part of nose is blocked.I have had almost all test like mont,liver function,chest X-Ray,vidal test,TLC DLC and all were fine.Can some one tell me what shld i do?is there any one who is having same problem.As my doctor said that u are fine and this fever is because of exersion and tiredness because i drive a long distance to my office,but i know that i am not 100% fit and i have found changes in body in last two months i am not the same as i were two months ago.
