Hello, so I've had some kind of uti over the last 2 weeks. I was unable to get to my gp as they were closed over the Xmas/ny break, so I ended up doing a telehealth consult with an after hours gp. Obviously they couldn't take a urine sample but gave me course of triprim which I thought was working but wasn't....the frequent weeing has now returned and I'm on a course of cephalexin. My regular gp is back and did a urine sample...I feel as though the cephalexin isnt working either...I'm still frequently weeing and I've got back pain. I've got not foul smelling odour, no burning...does this sounds like a stubborn uti or kidney infection?? My back isn't sore when I touch it, it does feels like I've pulled a muscle or have a cramp of some sort...plus I also have my period so I dont know if my usual period pain is on overload because of my uti.......help....
