hi,
thank you for providing the brief history of your brother
A thorough neuromuscular assessment is advised.
Based on your history it appears that due to high consumption of alcohol the nerve has got affected and entered the neuropathy.
further more, along with Medicine try doing
physical therapy along with the same. Usually a combination of medicine and physical therapy helps to improve the functional ability. Also, medicine prescribed are symptomatic and one need to focus on long term rehab.
Along with physical therapy there will be an improved
metabolism, muscle strength, immune system, etc.
In my clinical practice I advice my patients to undergo a combination of both as it clicks better.
Also, check the blood sugar level at regular intervals using the laboratory as electronic device may misguide you due to errors. Check the kidney function test and
creatinine levels too.
Performing an diagnostic
ultrasound will help to see the functions of the liver as well.
Working out with proper ladder for the symptoms will help plan a better
rehabilitation program.
