Hello

Thanks for the query.

Regarding the weakness and the numbness of the leg when a patient is on a plaster indicates compression of the peripheral nerves supplying the limb. Probably this is due to high pressures in the compartments of the leg which hamper the blood supply to the nerves and cause pressure injury to the nerves.

Most of the times this is a temporary problem and recovery often occurs in 3-6 months time. The presence of reduced parameters on the good physiotherapy. Take multivitamin supplements to accelerate the nerve recovery.

I am sorry you are dealing with this frustrating concern and I hope you can find yourself in better health soon with the help of your neurologist and physiotherapist.

I thank you again for the query. I hope you found my response to be helpful and informative. I you have any additional concerns I would be happy to address them.

Sincerely,

Hello,
Thanks for reverting back.

Regarding the recovery in neurological problems, it usually takes a long times like few months to years sometimes. MRI and other relevant investigations pick up the changes only when the problem is beyond certain limit. For example, peripheral nerve damage can be picked up only if is damaged by more than 50%. Every investigation has limitations in the field of Neurology. Hence, clinical history and examination scores over the investigations like MRI.

I thank you again for the query. I hope you found my response to be helpful and informative. I you have any additional concerns I would be happy to address them.

Sincerely,
