Hi everyone I'm new here and looking for some feedback. Started Humira Friday evening. Monday about lunch time I started to feel extremely cold, pain in lower back, spread to spine and neck, headache, extreme lethargy and slightly quickened breathing. legs and arms tingling. Had experienced a severe anaphylaxis to an iron infusion so I know it wasn't that severe however I think it was a delated reaction of some sort.Has ANYONE ever experienced any type of delayed reaction, days later like me, to their Humira? Doctor is sold this is what it was BUT me and the emergency room crew do too. Thanks!
