I have vitamin D deficiency with 4.2ng/ml, HbA1c at 5.7% and average blood glucose at 117mg/dl, fructosamine at 295umol/l(above normal), calcium is 9.96. I have terrible tingling and burning sensation in both my arms and legs. Not able to sleep as it's more at night. Taking matlida forte which reduces pain for few hours. Went thru enmg and nerve conduction which came normal. No proper diagnosis still. Sometimes I feel weak and muscles ache.lose concentration . The only medication right now is Matilda forte(daily one) and d3 60k per week. Night there is no relief as slight tingling and pain persists. Help please
