4 weeks ago I got the flu and a chest infection, it lasted about a week until I started to feel slightly better. As soon as I started to feel better I got a fever again, went back to the drs and was told I had a secondary infection so was put on antibiotics. Finished the antibiotics on Thursday and then woke up on Friday feeling slightly off again, then today have woken up with a really sore throat and temp again. I'm guessing I've picked up something else.
Surely it's not normal to get three different illnesses back to back. Should I be worried that my immune system is low or something ? Or are other people experiencing this and it's just a bad time for bugs?
