Botox is best known as a cosmetic treatment, but it also has a role in managing several MS symptoms. Injections block the nerve signals that tell nearby muscles to contract, which can calm spasticity in areas like the ankles, wrists, biceps, shoulders, and hips, and may also help with overactive bladder, tremors, and migraines. Relief sometimes shows up right away and sometimes takes a few weeks, typically lasting three to four months before another round is needed. Side effects are usually mild, such as bruising, soreness, or pain at the injection site, though bladder injections carry a risk of urinary tract infections or trouble emptying the bladder. Botox is generally not a first-line option — doctors tend to consider it when other medications have not worked well enough or have caused difficult side effects, and severe spasticity may not respond well to it.
