Your mix of tingling in hands/feet, burning limbs, poor concentration and that odd minty-cold feeling after gallbladder surgery points strongly to a nutritional neuropathy -
B12 and
vitamin D deficiency are the usual culprits, and post-cholecystectomy absorption problems make it more likely.
Thyroid dysfunction and early
diabetes/prediabetes also give exactly this picture, especially with high BP, fatty
liver grade 2 and raised
triglycerides. Dry palms and soles plus scleral changes need direct examination, so get the eyes seen once by an ophthalmologist. Please get CBC,
HbA1c,
TSH, serum B12, vitamin D,
creatinine and a
lipid profile done, and go to a hospital immediately if you develop weakness of a limb, slurred speech or facial drooping.Do the blood tests above, then book a consult with me on Practo with the reports so I can start B12/vitamin D correction and sort out your BP and fatty liver together.
