Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You have got diabetis, got treated, and now you could controle with diet and exercise. You are thinking so after some time with natural remedy you will get recurance of diabatis . with out your knowledge. So every diabetic with medicines or with out should get the blood sugar test done every month.
Your symptoms appears to be more of diabetis rather than the allergy
. I advise you to consult a physician for diagnosis and treatment.
Wishing for a quick and complete recovery.
