Hi I have had burning sensation when I pass water . I am STD NEG as have been checked , I ve noticed this has gotten worse and now I can see what looks like skin Bits in my urine , not a bad odour but I ve noticed a difference from usual urine smell , pain in but cheeks , I am on antibiotics and am 4 days in for a 7 day course and doctor has sent my urine away as she said in a test at the clinic that there were blood and protein in my urine. I lead a gym healthy life and I probably have too much protein in my diet . What do u think and also I had chlamydia 2 years ago and it seems that all this has developed since then when I was cleared of it . Too much protein ? But what has caused this infection with the burning if it is that ? The pain in but cheeks developed with the chlamydia and burning prompting me to be checked , this was a year ago now and since being cleared I am still having this sensation and the above other symptoms have developed. Many Thx
