Gentlemen,I apologise in advance for bringing up a subject that has been previously discussed but would appreciate some input. I suffer with severe arthritis and also have a fairly serious heart condition.I can`t take anti inflammatory`s and take Tramadol with Paracetemol for the arthritic pain and this is my concern,I know Tramadol can be habit forming. Several years ago I was given slow release patches for the pain but had a reaction that scared me,couldn`t sleep,itching so much I drew blood and was generally as high as a kite,after that I was put on Tramadol. If anyone is using patches currently how do you find them?What if any are the side effects with emphasis on their effect on heart rates,[do they increase it}What are their names? I ask about heart rates because the problem I suffer with is tachycardia for which I have a defibrallator fitted. Thank you Tafft.
