So I have been constantly unwell for the past month and a bit, I've had stomach issues which I was diagnosed with ibs for, I've had tonsilitis and a horrific stomach bug all in the space of 4 weeks, I am so so run down and stressed. I constantly have a feeling of weakness/general unwell and feel I can't function. My symptoms almost match cfs which I pray it is not as I know the treatment options is limited, I'm really concerned that something is not right with me in general as I'm sick so often and now I just feel stuck in a rut of feeling really weak and unwell with no apparent cause. Doctors prescribed anti biotics as they thought maybe tonsilitis didn't completely go but I have one day left off them and I still feel as awful as I did when I first took them. What could be causing this?
