Pruritus in MS can be tricky to treat. If the itching is mild, treatment is usually unnecessary and the symptom often goes away on its own. If the itching is severe, prolonged, or disrupts your daily life, talk to your doctor about possible treatments.
It is tempting to scratch the itch, but resist the urge because scratching may actually increase the feeling of itchiness. Scratching too hard can also cause problems such as broken or damaged skin that bleeds or becomes infected. And if the skin is itchy, but also numb, then you might cause a lot of damage before you realize it.
Instead, you may want to experiment with applying ice or cold packs to temporarily relieve the itching. Cold seems to override the itchiness and “confuse” the already mixed up nerve signals. Never apply ice directly to skin (always wrap in a towel or washcloth) and never leave ice on one area for more than 15-20 minutes at a time.
