The tingling sensation
, pin pricks, skin lesions can all occur due to peripheral neuropathy
. The common cause for this is Vitamin B12 deficiency
. Please get it measured.
You may start taking over the counter multivitamin
supplements like Zincovit, Revital 1 tablet a day after food for next 3 months. Look for improvement in your symptoms.
The other causes can be Diabetes, electrolyte imbalances like potassium and calcium imbalance. These need further evaluation and correction.
Hope this helps.
