Is this medicine malpractice?

Hello all, and sorry for a long story but just looking for guidance. I was born with a rare disease called Blue Rubber Bleb Nevus syndrome(BRBNS). Now this isn't really the cause of my issues but it played into it. About 4 years ago everything started, first I was having vicious headaches and after seeing doctors I was out on Vicodin which to a degree assisted with the issue. But this didn't go away so I started going to one of top hospitals in USA. Because of the BRBNS I have I was instantly seen by 12 doctors at a time for the rarity of my disease which only effects my leg. Well from there I was sent to see many doctors as mri showed malformations in my left temporal lobe and brain stem. I seen atleast 20 doctors in weeks at this place. One of them was a headache specialist that was not approving of Vicodin and wanted me to switch to Valporic Acid, she also injected me with a test medicine that is not in my records at all. Please understand at this time I was having a hard time. So I did what I was asked and switched meds. This medicine caused various issues to the point of falling down stairs. My regular doctor who really cared about me that I seen at a Health Department was extremely worried about this medicine as she was always on top of my health issues. She found that Valporic Acid thins the blood enough to cause hemorrahg. I stopped immediately, at my next mri bleeding was found in my malformations and I started to have seizures about 8 every time 12 hrs where I was just gone from my mind and seen it myself after staying at the main hospital for a week. A month later I was notified of brain surgery requirements. My seizures have drastically reduced. My question is, if this was all caused by Valporic Acid from a doctor who thought the pain medicine I was on was the worst but her med caused everything, is there anything I can do? I don't want others in this situation because some one couldn't verify their history. Please share your thoughts I'd greatly appreciate it.
