Adhesions/Scar Tissue

When I was Decompressed in December, my NS said that they had to remove a large amount of adhesions. I am wondering if those adhesions could be back! I am having a lot of sx and my neck, back of my head etc are killing me. I just went to my PCP today for another round of muscle relaxers. I can not sleep well at might anymore because I am so uncomfotable. Has anyone had any issues with adhesions/scar tissue? What was the route that your NL or NS decided to take? I am just curious...Thanks!
