Could the pain that is felt in a left butt due to nerve damage or sarciatica hurt if you press on .plz advise.?

Piriformis Syndrome: This is usually the result of the piriformis muscle squeezing the sciatic nerve and causing pain... Please check it out online. Take a warm pack and sit on it for about 10 minutes. Then don't forget to sit on ice for 10 minutes. Do this twice a day for seven days, and see if you get better!

Yes, but many causes: Pressing on or stretching the sciatic nerve in the buttock area can cause pain if the nerve is injured, or if there is muscle shortening and pinching, or if the nerve is irritated farther up in the spine such as a disc herniation. If there is pain down the leg, weakness, numbness, or tingling, or if you experience bowel or bladder leakage, you should see a doctor for diagnosis and treatment.

Piriformis Pain: The sciatic nerve runs underneath the piriformis muscle and typically does not irritate the nerve. However if the muscle is irritated or the nerve runs through the belly of the muscle (5-10% of people) it can press on the sciatic nerve and cause the sciatica type pain in the buttock region but also radiate into the leg as well. Typically stretching and nsaids are mainstay for treatment.
