A member asked:

Can tight hamstrings cause sciatica without any involvement of the piriformis muscle? (pain in the upper part of my leg after sitting over 3 hours)

Dr. Edward Hellman answered

Specializes in Orthopedic Surgery

Opposite: It is actually more likely the.other way around. Chronic "sciatica" will cause a person to lean forward and not fully straighten out at the hip and knee which can potentially lead to hip flexor and knee flex ion (hamstring) contractures; not typically the other way around.
