I've been on Remicade for roughly 2.5 years. Since my doctor upped my dose from 400mg to 600mg and 8w to 6w I've had bad reactions for first 2 weeks following each infusion(bone/Muscle pain, fatigue etc). My doctor just called saying my ANA blood test came back positive and I'm being sent to a rheumatologist now for further testing. I'm terrified what this means. Any insight?? Could this be nothing?
