Does sciatica always follower a path or can it start in the bum miss a bit of thigh out then start again further down the thigh or leg?

Sciatica: You can feel the pain either in the lower back or radiating to one leg as far as the toes and is exaggerated by coughing sneezing or laughter usually severe limir your movements and even common anelgesic will not take it away.

Sciatica: There may be collateral innervation from other nerves that supply some sensation to different areas and you just do not feel the pains ANS tingling as much in those areas, so a sciatic nerve irritation/inflammation/pinching may cause sporadic patterns down the leg area affected and supplied by the nerve. Hope this answer helps.

Sciatica pain: Sciatica is most often caused by a herniated lumbar disc usually starting in your bum and radiating down back of leg to foot with or withou tingling and numbness. Need to get MRI and determine what pathology is or is not present. So simple answer is that depending on pathology will determine levels of pain/discomfort.

Yes: Depending on which part of the nerve is irritated it can skip some parts of the leg and be evident in other parts.
