Hey guys hope you are feeling great. I've been having pain in my tongue and herpes on my lips. I think its cause of the B12 deficiency since I had that before. I wonder if it has something to do with Humira as Im on it for 1.5 months. Anyone had a similar experience or can relate B12 with Humira? I also advise all of you to have regular vitamin check ups because they usually are less considered among other factors but still has massive effects on our body if we lack the vitamins.
