Hi, welcome to this forum! I think you will like it a lot. It is so supportive, and nice to talk with people who have the same experiences you are having.
Take a look back about 8 posts or so, to one called Decompression Surgery: Pre op question to ask. Tuesday, May 10. YOu will see all my answers there (in blue), plus some comments from a following poster (sutan.)
Also, use the search engine on this site, write OD, Surgery, and see what pops up. There is a lot! Put lhc11 in the search box. She had a nice narration of her experience.
Do you know if your post op appt is one week or two? So read some more, write back with more questions!
