New member here on Spine-health. I was disability retired from active duty in 2015, after over 21 years of service. I had L4-S1 fusion and related discectomies to correct a herniated disc and L4-L5 spondylolisthesis, which resulted in right epidural/foraminal scarring and right L5 radiculopathy--my primary disability/medical retirement cause.
For over a decade, I have had a persistent pain in my right sacroiliac joint area and just below the joint with right testicular/scrotum pain and, more recently (last 2-3 years), voiding problems (start/stop problems). This pain pattern was NOT affected by my fusion surgery. I just received the results of my first ever sacroiliac MRI (have had several lumbar MRIs), which stated that my piriformis muscle on the LEFT is larger than the right, extending greater (left>rt) into the sciatic notch, which is "indicative of piriformis syndrome." Since all of my pain is on my right side, my question to the forum members is this, has anyone been disagnosed with piriformis syndrome where the piriformis on the painful side has atrophied (gotten smaller compared to the other side)? From all of the research I have conducted, piriformis syndrome tends to make the affected piriformis hypertrophy due to sciatic nerve entrapment. I just moved to a different state and have no continuity of care--I was not able to discuss my MRI results with the ortho doc.
