Can anyone help, yesterday I went to casulty for the second time in a year with a feeling that I was having a heart attack, ie. Chest pain, shoulder discomfort and tingling feeling in my arms and legs. After a four hour check I was cleared. However I still fell very unwell, in addition to the above, I also have the following symptoms, Light headed/faint feeling when driving or when standing suddenly, very strong urine, lower back discomfort and I feel as though I'm dragging myself around. I am a relativly fit 40 year old man, have a good diet, I dont smoke, I do consume more alcohol than the recommended amount, but generally consider myself to be in good shape. I have had a past history of depression and took a very large dose of Effexor XL for several years but have not taken any medication now for three years, some of the symptoms I am currently experiencing are very similar to the withdrawl symptoms I experienced three years ago !
