Hello , I am currently taking Duromine 30MG . I have been on Duromine for two months, through out that period I sometimes got a tight chest nothing serious and it wouldn t last for more then 3-6 hours.. I stopped taking Duromine to give my body a rest for two weeks.. I am now on my third month of 30mg ( second day) and I ve had a really tight pain in the left of my chest when I breathe ? I feel okay no pains anywhere else.. This has been for the past 24 hours . What should I do? I am a smoker and drive 1-2 coffees a day but I also am healthy don t drink alcohol or have bad foods. I haven t taken the pill today because I m a bit nervous as I haven t had the pain last this long before . It s only when I take deep breaths in and out it hurts.. My doctor told me this was a normal side effect but it s been longer then 12 hours and I haven t taken the Duromine tablet in 12 hours. Should I continue to take it when the pain goes as my weightloss has been successful? Should I go to emergency?
