Well I am 5 weeks post op LTHR , I can truthfully say NOTHING has hurt like this UTI infection, I just got back from dr got 2 shots and presciption for keflex 500 mg which he said would treat both, I apparently have had this for a bit but man overnite it exploded and miserable over weekend. I am also taking azo tabs dr said it would help with pain of uti. My question how long does it take to start noticing any kind of relief. Seems ever since I got my hip I have been sick with sinus and now this ,Thank god my hip feels great , the only bright light , First thing dr asked is did I have a cath. in hospital I told him for 2 days , Is this common after surgery? I am sure the sinus infection has to do with weather I know everyone is differant and responds diff. but like shpuld I see improvement within a couple of days and will the 2 shots of antibiotic help it work quicker. Thank so much for your answers in advance & God Bless!
