Hi! In my personal opinion, I have found that trigger point therapy (sometimes called neuromuscular therapy) can be quite effective in eliminating sciatic like pain. It is also comfortable for you as the client to receive treatment in the tailbone region. This modality can be administered over the clothes. The goal with trigger point therapy is to seek and destroy trigger points and their associated pain referral pattern. The therapist will locate the trigger point, with your guidance, and apply prolonged pressure until the referral diminishes. This essentially tells the brain to stop bombarding the muscle with excessive stimulus and thus, deactivating the trigger point. I hope that helps!
