I'm 23 years old.  A couple days ago I drank a little bit too much, and started to notice that during that time my ankles started to hurt.  I woke up the next day and and my ankles still hurt and my feet were tingling.  I woke up today and still had the same problem, except now it starts at the top of my butt and goes down to my ankles.  I'm also experiencing a problem achieving an erection since then.  I started smoking about 3 months ago and am planning to quit now.  I'm afraid I have some nervous system problem or heart disease and that is why all this is happening.
