PLEASE HELP. My mother is stuck on the floor of her bedroom-SEVERE Back Pain?

If she is in that much pain she needs to goto the hospital. Going now while it is still hurting may revel somthing that other doctors have missed. But since she is refusing even if you call 911 if she is fully alert and orentinted they cant make her go. You should call a doctor or goto an urgent care clinic, if its a musscle pain try ibprofen, other pain you can try tylonol. Heat packs work well, Dont use cold after 24 hours after an injury. If the pain consist for more than 48 hours or wakes her up at night she needs to goto the hospital (and maybe you should try a differnt hospital)
