I had my first infusion of Carbo/Alimta on 2/20 with the usual premed. Since the first day after chemo, I 've had even more severe pain in my left upper back and down my arm - in my ulnar distribution. I didn't have such severe pain even before chemo and it was controlled with 2 tabs Vicodin/over 24 hours along with 300mg Gabapentin. Now I take 2 tab Vicodin and 400mg Gaba at night, along with Ativan and I still have severe pain. It makes me feel there is a lot of swelling inside causing more nerve compression. The pain is really intolerable and I have emailed my doctor. Has anyone ever had any experience like this? How much longer will this pain last?
