do a L Shaped bend too much. How long does it take for me to do this... I feel extremely tired lately [am quite physically active] when working on yard. I have a pinched nerve/ sciatic nerve pain all of a sudden a month++ back and doctor mentioned I have a L4-5 herniation with stenosis. He recommended a decompression. No discs were removed just a simple surgery... yet it was quite painful/ a hassle moving during the first 7-8 days... after that it was ok. ideas when my still slight numbness and bending over will last or can I do any stretching exercises yet??
