Welcome to HCM.
Your's is a very sad story of failed surgery. In many trials treating the patient conservatively , had favorable results compared to surgery, in the long run. You need to speak to a good physiotherapist for a decent rehabilitation
plan. I also suggest that you see a neurosurgeon for a second and perhaps even a third opinion. I stress
again that exercises and pain management are better than any more surgery. I trust that this information helps you.
