Low fever since more than 3 month.

Fever started in june 21 around 101 then went to physician. Fever supress during medication but once I stop medicine then it came again. But it usually used to go 99.5 and sometimes reache to 100. Had UTI problem in one year back so went for Urine test and scrotum ultrasound. Ultrasound was normal.Epithelial cells range was 6-8 so went to urologist.he checked and did physical examination but didn't find any concerns. For 2 weeks again took antibiotics but once medication stops then again fever came..but again it used to go max to 99.5 and rarely reaches to 100. Went to homeopathic dr.he suggested to go for urine test and typhoid test.. Typhoid was not there and Urine reports was normal. He suggested medicine for Fever for 2 weeks. For first 11 days did not feel fever but again fever came around 99.4-6. Fever usually comes  in day or two in one time in day and in the range from 98.6 to 99.5. I have vitamin D deficiency and haemoglobin is 11, SGPT is 56.rest all is normal. Please advice.
