Medical malpractice

I currently suffer from Severe Spinal Stenosis. I recently became divorced because of it. The Doctor I am seeing recommended disability due to my condition and not having the ability to walk unless assisted and/or stand and cannot carry items. Also have no feeling in my left leg or foot. I am on many prescription pills to combat the chronic pain and muscle seizures I have. I have already gone through 4 surgeries on my spine. The doctor recommended I go on disability and also provided me with a disability attorneys information. I had a court hearing in regard to me being disabled and for maintenance since my now ex-wife did not want to deal with me after all of my back issues arose. The doctor stated he would testify on my behalf, but I would have to pay him extra. After having my family pay the doctor to testify (I have been out of work for 3 years as the company let me go due to me not being able to perform my job duties for my disability) He came to court and testified against me stating I was not disabled. This in turn caused me not to get maintenance and also lost disability as I was already on it at that time and after his testimony, disability rejected me. Would this be a kind of medical malpractice? Being lied to and mislead especially after requesting additional money for non-medical services?
