I have been on Humira 18 months and had this happen for the first time after my last shot. I actually thought it might have been the start of shingles as I had been in contact with someone who has just been diagnosed with them. I didnt realise this was a side effect from Humira.
When this happened to me I felt quite warm and my chest was hot - then I had the 3 blister like lumps on my chest - not sure if this is what you had.
I take my shot again this Wed. so will monitor what happens from then.
Thanks fors posting this as I would not have had any idea that it was the Humira doing this.
