I have been suffering from a herniated disc for the past 3 years now.  3 months ago I suffered some excruciating pain from this condition.  The pain went away after about 24hrs but ever since then I have been walking with a slight limp, I have very little strength in my right calf and my lower leg swells up every day after walking for about an hour.
