What Are Botulin Injections?
Botulin injections are a non-surgical procedure which is used to treat spasticity. Spasticity is an upper motor neuron disorder, which affects the nervous system and is associated with muscle contractures. Without treatment, spasticity can cause pain and deformity. Untreated spasticity can impair function, quality of life, and reduce the ability to perform everyday activities.
Botulin injections work by blocking the nerve signals that control muscle movements. These nerves send messages to the muscle through acetylcholine. When this chemical is blocked, the muscle relaxes. The effects of the injection can last for a few months. However, a repeat injection is necessary to maintain the effects of the medication.

Botulin injections are not painful, and most patients report little discomfort. They require only a few minutes to complete. To numb the area prior to the procedure, a topical anesthetic is applied.
Botulin injections typically take between three and 10 days to begin working. In some cases, the effects will last for up to six months. However, in chronic conditions, a repeat injection is usually needed every few months.
Botulin injections can be used to help control bladder leakage. The procedure is done in an endoscopy center. During the procedure, the doctor will insert a small camera into the mouth. This camera allows the doctor to see where to place the injections.
The most common side effect of botulin injections is temporary bruising at the site of the injection. A small amount of bleeding may also occur inside the stomach.
