My Husband Was Amputated In 1990 Below The Knee. A

My husband was amputated in 1990 below the knee. A couple of years after surgery he started experiencing nerve spasms. We have consulted many orthopedic doctors and all of his other doctors and no one has ever mentioned a Traumatic neuroma. He now has PD and dementia and a number of other Agent Orange related conditions. Over the years, he has dealt with these spasm attacks, relentlessly. He has been in the bed the past two days with nerve spasms. It seems the PD is effecting this condition. Who do we need to seek out for help???
