What happens during and after the procedure?
Botox or Myoblock injections can be done in the office or under sedation at an outpatient surgery center. Where the procedure is done depends upon the size and location of the muscles injected, personal preference, and insurance coverage.
In the office setting, you will be asked to change into a gown and to lie down on an examination table. The skin will be cleansed with a sterile solution. The muscles in spasm will be injected with the solution of the botulinum toxin mixed with either saline or local anesthetic (numbing) medication. If necessary, "band aids" will be placed over the injection sites.
In an outpatient surgery setting, an IV will be started so that relaxation medication can be given. You will be taken to a procedure room and positioned lying on your stomach on a procedure table. Monitors will be placed on you to watch your heart rate, blood pressure, and blood oxygen level. For injections in deep muscles such as the piriformis, psoas, or scalene muscles your doctor may take x-rays to ensure proper needle placement. A solution of Botox or Myoblock and local anesthetic is then injected into the muscles. You may experience temporary numbness or weakness in a leg with the piriformis or psoas injection or in an arm with scalene injections in the neck. After being monitored in the recovery area, you will be discharged. Due to the use of relaxation medications, you will need a driver to take you home.
Temporary side effects from the injections may include increase in pain, weakness in the muscles injected, body aches, dry mouth, and hoarseness. Your physician will recommend timing for a follow up visit in the office.
