Do the injections hurt?

Attention is given to making your injections as painless as possible. Before any needle touches your skin, the site is sprayed with a topical anesthetic to numb it and then injected with lidocaine to numb the needle track. The guided injection is then administered with the smallest possible needle using an injection approach rated least painful. However, for those patients who desire even more comfort, nitrous oxide (laughing gas) is available during the procedure.
