Thanks for all your replies everyone... I'm still in a lot of pain but i've also still been really busy as I can't miss any work at the moment, which is also why I haven't logged onto here since I last wrote.
I'm persuaded.. I'm going to the doctors tomorrow and I'll take the antibiotics. That's a good point Noctula that I should take these ones and then reduce taking more if it gets worse! I just wish there was something else to sort it. It's far worse at night.
Urgh. Thank you very much again.
