- Muscular trigger points several muscles in the lower back and buttock commonly refer pain into the buttock and leg and can be surprisingly painful. These tend to give a deep achy type pain and can be secondary to a lower back injury.
- Joints of the lumbar spine 'Between every level of your spine there is a small joint on each side called a facet joint. When inflamed, facet joints will also cause pain to radiate into the buttock and at times, upper thigh. This is different to sciatic pain however as the sciatic nerve itself may not be affected at all.
- Upper hamstring tendon 'The upper hamstring attachment into the sitting bone of the pelvis is another cause of pain easily confused with sciatica. When this tendon becomes overloaded it can cause buttock and thigh pain and become very uncomfortable especially in sitting.
