I'm a newbie here. This is my first post. I'm 9 weeks post-op L3-S1 fusion & discectomy (sorry, I don't know all the abbreviations). I have a LOT of heaviness in my pelvic area and thighs. Plus pain in my left butt cheek. Is this normal? I am also in a lot of pain when I try to walk very far. I am supposed to return to work on Dec. 16 (at 12 weeks post-op) but I am wondering if that is reasonable given how much I have to walk and be on my feet as a 2nd grade teacher. Any input would be greatly appreciated!
