HI, thanks for using healthcare magic
Based on your description, the pain may be due to
neuralgia which is nerve related pain.
There are different possible causes such as: (1)
vitamin b12 or folate deficiency
(2)diabetes
(3)trauma
(4) liver or kidney disease
(5)side effect of medication
(6)neurological diseases such as stroke or ms
(7)infections eg shingles
(8)idiopathic- cause not known
(9)some
hormonal disease eg
thyroid disease, some autoimmune disease
Blood tests for diabetes, kidney or liver disease, checking for infection, vitamin b12 or folate level may be needed
I hope this helps
