Can Botox be injected Into the buttocks to reducing muscle tightening?

Botox can be injected into almost any muscle to relax the muscles, but the buttock is not a commonly injected area. You need to consult with a provider who is intimately familiar with the anatomy of the buttocks. 

Dear Modest6610,
Botox is an injectable muscle relaxer. There are other specialties outside Plastics, ENT, Neurology, Maxillofacial, Ophthalmology and other specialties which use it to rebalance spastic, tight and contracted single and partial muscles and muscle groups outside of the face and neck. Please consider a Board Certified Physiatrist (Rehabilitation MD / DO) and / or Orthopedic Specialist with this training. Good luck!
