Starting Remicaid in three weeks...HELP

I have had RA now for 1 year. Still not under control.. I take MTX once a week, Ultram, neurontin, folic acid, and lortab when needed... Enbrel worked at first for about two months then a few months ago my levels went back up.. So it is on to Remicaid.. Has anyone had this problem of one not working and then another will? I also have a stress fracture on my left foot... Have been dealing with that for a year now also.. It wont heal.. Has anyone had and fractures that wont heal? Or anything similar.. Just looking for some suggestions or stories of your experience// I am nervous of doing the infusions, so anyone with info on that please share...Thanks to you all... I love this site it helps so much to know I am not the only one dealing with this, since noone around understands...
