Result of atherosclerotic plaque blocking one or more of the blood vessels that supply the heart. Can cause chest pain/angina pectoris occurring due to stress of exercise. If blockage completely impedes blood flow to the heart, a heart attack can occur.
It can be caused by insect stings, food, or medicines. It's caused by the release of histamine into your bloodstream and tissues. Histamine is an immune system chemical. Tongue or throat swelling can happen along with an allergic rash (hives), wheezing, diarrhea, and shock (low blood pressure).
Glossitis can cause the small bumps on the surface of the tongue called the papillae to disappear. Your papillae play a role in how you eat. They contain thousands of tiny sensors called taste buds. Severe tongue inflammations that result in swelling and redness can cause pain and change the way you eat or speak.
