More info about your health and medications would be helpful. Impotence can be caused by blood pressure medications, high blood pressure, diabetes, stress, hormone imbalances (yes, men get those too!), injury and also plaquing in the arteries. I hate to say this, but the first sign of impending problems with some of our cardiac patients was impotence. I don t mean to scare you, but you didn t give much info to go on. You do need to see your doc and have an evaluation done. It may nothing major and the doc will give you Viagra, Cialis or Levitra. If it is something that could be serious, you can get a handle on it and get it under control.
