The past 2-3 yrs i've experienced mild/severe burning at the end of urination. tested for stis, always came back neg. treated for uti but no relief. ?

See remark: If this is going on for 2-3 yrs ,i believe it is time to see a urologist.However in the meantime get AZO tablets from your drug store.It is available over the counter,no need for prescription.Take one tablet 3-4 times a day Hopefully you get relieve,and it may do the trick,specially if your urine has no infection Best of help to you young lady
