<s>[INST] Hi Im a nineteen year old female, a couple months back lets say in January of 2011 I ended up in the hospital twice because of  an overdose of Caffeine. Well anyways ever since that time Ive been having pain in my heart and when I place my hand on my chest I cant feel my heart beating and I have a low pulse when I check it, what can this be from? Is it a heart condition? And the weird thing is the last time I went in to the doctors they said my heart was fine, but yet I keep having this proble,... Please help. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. First no need to worry about heart diseases as your doctor said that heart is fine. In my opinion, your symptoms are due to gastritis and HERD (gastroesophageal reflux disease). Caffeine overdose can cause stomach problems like gastritis and HERD. And both can cause similar kind of symptoms. So avoid hot and spicy food. Avoid stress and tension, be relaxed and calm. Avoid excessive caffeine Chat Doctor.  Take pantoprazole tablet on empty stomach. Don't worry, you will be alright with all these. Don't worry about heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
