Hi I too have had a microdissectomy last August 2010 and still suffer with what I think is water retention. It sits just above my bottom and next to the scar. Sometimes it's worse than others. I find that doctors can be very dismissive or don't really understand and seeing a professional takes referrals, which I won't get. I'm still getting used to being able to do stuff and I find the mental barrier as every ache or pain in my legs or back worries me.
The good news is if you do take it steady and take the 3 months to recover you will be amazed how much easier it is to move and be able to stand without discomfort.
I'm pleased to find others that are going through the same thing. Please reply because unless you've experienced it no one can understand the pain and what it does mentally.
Take care and hope to receive a reply soon
