HI, thanks for using healthcare magic
The symptoms are in keeping with neuropathy which is abnormal function of the nerves.
There are different possible causes such as : (1) trauma to the nerves in the area. This may be the most likely cause for you.
An x ray of the neck , shoulder and left elbow may be needed to determine if any of these areas are involved
(2)
vitamin b12 and
folate deficiency
(3)diabetes
(4)liver or
kidney disease
(5)side effects of medication
(6)exposure to toxins
(7)infections such as shingles
(8)thyroid disease
(9)neurological conditions such as
stroke, ms
In addition to the x rays , blood tests may be needed if the x rays are normal.
The blood tests are vitamin b12 and folate levels, full blood count,
thyroid function tests, diabetes screening and liver function tests.
Treatment would depend on the cause found
I hope this helps
