hi,
thank you for providing the brief history of your father.
As i was reading the history , i feel a thorough neuromuscular assessment is needed for further management.
Also, you have mentioned he had
burn injury in the past, the degree of burn is needed and the exact site of burn need to be understood.
Now he is 65 years old so it comes in mind of two possibilites.
1. Undergoing the urine test which will help us to understand any uric acid higher levels and if so present the treatment will be guided towards the medical and
physical therapy. And patients recover 100%
2. If the urine test is negative, than an NCV of the upper limb as well lower limb will be performed to see the functioning of the nerve and any pathology. If the test is positive a proper medical prescription and physical therapy will help ease the factor.
Now if both this test fails, than taking an MRI of the cervical and
lumbar spine is guided, as to know the status of the
soft tissue of the spine and any
nerve root compression. Since his age is 65, there will be degenerative changes in the spine. Physical therapy has been very successful in cases with this. Also, by exercises, the Blood
glucose level , blood pressure,
metabolism and immune system will improve and provide the optimum health.
I have seen cases in my clinical practice and with a combination of medication and physical therapy there is 99% success rate. I wish the same from your father.
