Hi, this could be neuropathy, low calcium levels,
thyroid disorder, vitamin B deficiency, obstructive jaundice, autoimmune disorder or simply allergic manifestations.
Please get blood work done, SGPT, SAP levels for liver function, TLC and DLC for allergy, T3 and T4 for thyroid function, urine and blood urea for kidney function along with calcium and vitamin B levels. How old are you?
