help w raelynns medical

As some know 2yrs ago doctors dicovered raelynn had chiari and a syrinx and had brain surgery, several days ago she was rushed to er w severe head pain, and vommiting, after a ton of test and days in hospital, doctors discovered she has a build up of cerebellum fluid and they can not pull from it or itll make her brain lower and with her chiari itll cause her syrinx to return causing more dangerous and permanant damage and risking paralyzeing her, so they only thing they can do atm is give meds to help make her comfortable, im asking for help bc insurance only cover 1 of 8 medications and the main 2 alone are $300 even with paper work from her doctors they are refusing to cover them, and a few are over the counter but very expensive, and sadly im the only income at the moment so i cant afford them, ive been crying all morning trying to figure this out which is why im asking for any help she needs these just to be out of pain, the hospital gave me 5 days worth to get us going but shes going to need more then that, her pcp said it may take 30-60 days to get the insurance to finally cover it, and she cant go that long in that kinda pain so sadly imma HAVE to pay for 1st round any help is greatly appreciated -kaeline
