Many people use antacids to relieve a burning pain in the upper part of the chest called heartburn.
Ulcers are sores or irritated areas that develop in the stomach in response to infection or increased acid production. They can be small or large in size. Pain is common with them and antacids can be used to treat the pain and protect the ulcer from worsening. Other diseases can mimic the symptoms of heartburn. It is important to discuss any new symptoms with your doctor.
