I got a cold which developed into a chest infection 3 weeks ago. I got 7 days antibiotics which was helping but didn't quite shift it, and the next GP I saw was useless and said it should have been enough so to just go away and it would improve. It didn't, it got worse again so I returned and received another 5 days of a different antibiotic, which they will extend to 7 days if it's not quite done the trick. I'm on day 2 of the 2nd lot of antibiotics and I am feeling better than I was yesterday so I think the antibiotics are working. The GP has urged me to return to the surgery tomorrow if it I'm not further improved and suggested if that's the case I should get a blood test to check my immune system is strong enough to fight the chest infection/get a chest x-ray. I'm on Tecfidera, and my lymphocyte count is generally around 1.2 to 1.4 at the routine checks. Given it's lasting so long should I ring the MS nurse or is that not part of their remit? Any suggestions, advice or wisdom welcome!! Thanks :)
