My doc upped my remicade 2 weeks ago to 600mg from 400mg after about 5 days I started to get really bad bone pain in my back/ribs/jaw/shins etc and I noticed a swelling fatty mass on the upper left ribcage just below my breast any thoughts or insight?? I had bloodwork and chest X-ray and ultrasound and my doc said it's not cancerous but I'm still feeling ill. Having a tightening in my rib cage über both breasts and still gave back pain too. Thoughts??
