OK, its not actully the epi im asking about but similar to...

About 3-4 weeks ago now DH had a spinal tap done....(which is pretty much an epi only they take fluid instead of putting fluid in) and he is still in pain from it. His back constantly aches and sore to touch.... still very bruised.

I guess what im asking is:

Has any one thats had an epi suffered these kind of things this far down the track..and is it something to worry about or is it normal?
