So for nearly 3 weeks been ill on and off kept getting really sore throat then it would clear for a few days then start hurting again, feeling really drained with painful legs (bizarre?) then a few days ago developed a horrible cold.. On top of sore throat crap. Went to doctors today didn't really understand her an she didn't actually tell me if I had a infection or anything just mumbled about if viruses go on for so long sometimes they need antibiotics but not all the time.. Then gave me them anyway. So I took first one about 2 hrs ago clarithromycin they are called. Now I feel breathless an weird and my hearts beating funny I'm scared. I read up on a forum before I took them an a lot of people who wrote on it seemed to have had funny turns on them !! X
