Hi, I had meningitis when I was 4, I'm almost 22 now but my immune system is still really weak. I was in hospital for a couple of months with it and made a full recovery but my immune system has never been the same since. For the past few Autumn/Winters I have suffered with a persistent cough for up to 3 months at a time. It usually starts after a cold, but hangs around for an awful long time after the cold has cleared and it doesn't ease. It always feels like I have something sat on my chest that I need to cough up. Just wondered if anyone had experienced anything similar and whether I should get it checked out??
