I have taken extacy before 2 years ago for about 4years. I was taking ex everyday. I would take 3 to 4 pills and once I even took 12 pills. I quit 2 years ago and just in the last month started again. I suffered from memory loss, anxiety and weight loss from the last use. now I am experiencing pain around my heart sometimes waking me from sleep. I have had a 2 week dull headache and a little difficulty breathing. I m confused because I expected the back pain, memory loss, weight loss, difficulty sleeping ect.. But in the 4 years of use never these new pains. Will this go away? Am I at risk for a heart attack? I don t have insurance, when/should I go to the ER? Other factors that may be important. Never had existing heart condition. Rhr on extacy up to 120. I m hydrated and eat before use. I smoke 1/2 to full pack a day. The pain last about a second and occurs in 5-10 min intervals. Except at night the pain stays the entire time laying down. There is also a pain in area around left armpit.
