I've been taking humira for over a year. This summer I started to develop cold like symptoms. At first I thought it was the weather/allergies. It progressed into a severe cough, congestion etc. Stopped the humira for a month and went on 2 antibiotics cleared up instantly and stayed clear. Started humira again last week and cold like symptoms are back it isn't severe yet but everyday a little worse, is this the humira? Do I need to be concerned?
