Woke up with severe pain in the center of my chest, thought it's a trapped wind, medication for that helped, however the pain remains, pain becomes severe when sleeping and bending forward,i take aspirin for pain. can a trapped wind cause pleurisy?

You have chosen bad: There are certain pain meds one should not use for stomach pains. These include Aspirin and Aspirin like drugs called NSAIDS(non-steroidal-anti-inflammatory Drugs). The latter nclude drugs like Ibuprophen (Motrin/Advil) & Naprosyn(Aleve), as these can cause stomach ulcers or Gastritis....conditions which are typically the cause of stomach pains. The best medicine to use in your case is Antiacids.

Pericarditis: These symptoms seem suggestive of pericarditis- which is when the lining of the heart becomes inflammed. Moving forward and experiencing a change in the pain symptoms is a characteristic, because the heart moves in the 'bag' surrounding it. It is very painful and sharp in quality like you mentioned. Pleurisy is inflammation of the lining of the lungs - so it's similar. I recc to see a doctor there
