Hi.. I have had MS since 1978.. been in Avonex, Copaxone and now for th3 last 3 years Tecifidera.. I seem to have more colds (2 a year) which each cold has a bad cough and seems to last 1 to 2 months long.. I am worried about my lungs. Also a lot of Flushing.. sometimes really red and itchy.. other than that, bloods tests excellent, energy good when not sick with a cold..
