Hi,
I was 50 when I had a L5-S1 infusion. I was playing tennis competitively three times a week, swimming on weekends, jogging and walking in between. I started to have backpain and I sought all kinds of options (chiropractor, acupuncture, pain management) but nothing helped. Finally I went to see an orthopedic surgeon. My MRI showed my pain was from a disc desiccation and degeneration and the disc bulge did touch both L5 nerve roos with impingement.
After the surgery, I had no more pain but my lowerback was kind of stiff (limited range of motion). I couldn't play tennis anymore and that was the only thing I missed as I was my husband's double partner 🙁 .
Hope this helps.
