Iam in anti TB drugs since five months, one tab of 50mcg of thyroxine for
thyroid too. Offlate iam seeing some black spots on both sides of inner mouth bed. They are a little rough too when felt with my tongue plus deep above on both sides there are bruises up on mouth bed that give a burning sensation when I eat even slightest spicy food. Why is it so? It's been a month now of these spots and they are not going. Please help.
