Thanks for your question and if you are having these concerns following a Restylane injection, perhaps your provider is not making you feel comfortable enough with your treatments or something else is going on. These injections have been performed for numerous years, and it is not common to have headaches or other problems following the procedure. You may need Tylenol or Advil once in a blue moon, but if you need something like Ativan, then that is something you should discuss more with your primary care doctor. Most of us would not give you this post Restylane. You should be seen by a board-certified dermatologist or plastic surgeon to assure the best possible outcomes and treatment plans.
As a Dermatologist, I would never recommend Ativan to control post-procedural discomfort. I recommend you contact your primary care physician and the doctor who performed your procedure and explain your symptoms.
