I Was Just Trying To Look Up Uti Symptoms And

I was just trying to look up uti symptoms and red bull or star bucks Frappuccino drinks you buy at the gas station. It seems my ureatha burns after drinking one large can of red bull or 2 bottles of the mocha starbucks coffee. It doesn't seem to be over my daily caffeine amount . I see a urologist in a month from now. My last uti test came back neg. I'm trying to find causes that would make my ureatha burn. Dr. prescribed nitrofur mac 100mg. at bed time to prevent uti. however I was feeling better and forgot I had the meds. But last night It started hurting and by morning it was bad again. I showered and took the Nitrofur. I don't have money to pay for an answer on this sight I came across in my google search. I'm guessing somehow it will cost money for any answer. Thank you. I have been dealing with this since the beginning of Sept. I'm 55 yrs. of age. And have Fibro, Ibs, Mixed connective tissue disease, and a very painful neck and back. Yep I followed the props and it does cost. I have no money to pay.
