Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having GERD (
gastroesophageal reflux disease) related chest pain. But better to first rule out heart diseases. So get done ecg. If ecg is normal then no GERD is more likely in your case.
Anxiety and Marijuana smoking are risk factors for GERD. They cause laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of chest pain, palpitations etc.
So first of all quit Marijuana smoking.
Stress management is very important to relieve GERD. So better to
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic drugs too.
Take
proton pump inhibitors and prokinetic drugs for GERD.
Don't worry, you will be alright. Consult psychiatrist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
