So this is my 3rd UTI this year previously was prescribed Nitrofurantoin-bad reaction then Trimethoprim-made me weak and trembly and put me in a CFS relapse for a month. Talked to the nurse who suggested Keflex but of course I have googled it and some people have had bad anxiety and racing heart with it. As I already have mild anxiety and palpitations I’m really scared to take it, has anyone on here taken it? I am trying to treat it naturally with D-Mannose but of course am anxious about it getting worse if i dont take AB’s. So stressed about it!
