Hi there ~ I understand your concerns. A combination of speed and heroin can make your condition worse with worsening of your gastritis which can appear as sharp pain in your stomach, or having a perforated gastric ulcer which needs immediate surgical attention. I believe the first point of contact for you is your local doctor who can help suggest medications and make the appropriate referrals. I hope you do so as soon as possible. I hope this helps. Take care and have a lovely day!
