2 Months Post Lumbar Laminectomy

Tell me how to lift now…

I will try to keep this short, here goes, Im a long time lifter a 33yr old male, and was on a good lifting streak until I really hurt myself 3 months ago hack squating 900 lbs, Ruptured my L4-L5 Disk and had to have surgury. I did considerd myself prettty strong before with a bench 415lbs, among other lifts, I have not touched anything for 3 months now since I got hurt. 2 months passed since surgury, and now my back is healing up, I go see my dr. in 2 weeks for clearance for Theraphy. Im nervous to go back to lift and do any type of squating in fear I will hurt myself again, Does anyone have any advise on this, and how I will regain size back in my legs/Gluts? I miss pumping iron…

Any advise suggessestions etc… would be appreciated.

Thanks.
