Dear friend, welcome to HCM!
Your mom has been prescribed drugs for Parkinsonism, a movement slowing brain disorder.
There is no nerve
contraction here. You may have overheard wrong thing.
The treatment is already prescribed. It is treated with medicines alone.
I think you are not counselled well.
Please requestt your doctor to explain the diagnosis and treatment plan in free time.
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
