Since Oct 21 I have had a recurring UTI which over Christmas spread to my kidneys. In this time I've had 3 days trimethoprim and 7 days nitrofurantoin (from the walk in over Christmas). Currently have covid but UTI was causing me bother so rang the docs. Had an app with a nurse who said they really shouldn't give me any antibiotics until I've sent a sample off (can't as isolating) but she decided she would prescribe 3 x 500mg cefalexin for 7 days anyways.
I am over half way through the course and have been in agony - intense stomach cramps have got me in agony, vomiting and generally dizzy and unwell (on top of the covid symptoms 
)
Has anybody had these side effects? I am concerned incase it's not actually the antibiotics causing it! Obviously want to finish the course regardless but am in so much pain
