I have frequent skin lose on my tongue its so painful when its peeled off and red and stings doctor gave iron tablet 3aday some skin not come back?

Skin on tongue: Impossible to say what the problem is without more information and a visual exam. It could be an infection, due to trauma, a vitamin deficiency, an allergy. You need to have this examined by a dentist or an oral surgeon.

See Oral Surgeon: Given the same symptoms that you describe, i would not think that prescribing iron tablets would be the solution. This requires a medical history and personal clinical examination. I would recommend that you see an oral surgeon for a definitive diagnosis and proper treatment.
