wondering where you got your information about piriformis syndrome? i had a chiropractor tell me (quite a number of years ago) that i had this condition. after a couple months of therapy from him and no relief in pain i had to visit an orthopedic surgeon (harvard graduate) who determined from an mri i had a herniated disc. he also told me that the condition of piriformis syndrome has only been known to occur in pregnant women!
When someone has sciatic symptoms, piriformis syndrome is generally not the first thing you look for. Herniated disc is significantly more prevalent. Generally, piriformis syndrome occurs in only a small percentage of people with low back/lower extremity pain. However, it is not just restricted to pregnant women.
You can tell if a person has a herniated disc or piriformis syndrome thru a few simple tests. If you stretch the piriformis muscle and it reproduces the symptoms, you have piriformis syndrome.
If the symptoms are reproduced with forward bending (reaching for the toes while in standing), the problem is probably a herniated disc.
Regardless, MRI is the gold standard, though, for diagnosing a herniated disc.
