Methodone Side Effects, I have had many trips to Emergency Unit at my Town, having tight painful heart problems. But when they do the Tests for Heart attacks, I jave always been told I have no problem my heart is fine. I have had ECG Tests, all fine. The only thing I can put it to ie: 250 milligrams of Methodone Tablet for Chronic Pain at the highest point was 50 x 5mg Tablest per day. I have had my leg amputated which I had the medication for. Can you confirm what I should be asking my GP, and what literature orResearch papers I can refer to. Thank you Geoff perry
