If he was that ANEMIC that he required that many bags of blood AND iron then, he needs to be seen for BLOOD LOSS issues which would include GI bleeding and then, on the other side of the equation, blood production problems which would include bone marrow
I highly recommend getting a consultation with a GI specialist and a HEMATOLOGIST/ONCOLOGIST
as he may also have some type of tumorous growth in the body that needs to be identified. I'm not sure why you would give him a shot of HUMIRA
unless it belongs to him and you were instructed to that.
Otherwise, if the Humira is something he only received based on your desire to help and he immediately got swollen gums
and face then, perhaps he's having an allergic reaction
to that medication.
Hope I have answered your query. Let me know if I can assist you further.
