Hello fellow MSers, does anybody have any tips on fighting colds while we take certain DMTs which lower our immune system? I had Omicron about 4 months ago and thankfully recovered, but since then I have started Kesimpta and have just finished my first month of injections. For the last 3 weeks I have had the sniffles and what seems like a constant runny nose and can't seem to shift it. I was hoping to speak with my nurse this week but they never turned up to the pre booked appointment so thought I might ask on here to gauge any advice or tips. Also has anybody been contacted by their Doctor reference a 4th Covid booster jab yet?
