Would you be able to see a change if your tongue was swollen i'm always scared mine will swell i have thyroid problems gerd and vitamin defficiancy?

Tongue swelling: Not a consequence of problems you stated. Get professional help. See endocrinologist for medication to control thyroid function. See gastroenterologist for rx to control gerd. See your gp or a nutritionist if lab tests show that you truly have a vitamin deficiency. Multiple problems requiring multiple solutions...Get help from the pros...You can't do this by yourself.
