Hi SL -
You may have better luck with this question in the Dermatology forum. Here's a link.

Just want to add that although IV steroids are often used for MS flares, that's not their only use. Since this is an MS forum of members who either have a diagnosis of MS or are in process of being evaluated for it, we really are not knowledgeable about other kinds of symptoms.
If I were you I'd take mom to an ER, where she can get, we hope, much quicker relief.

Sounds like shingles which needs to be treated with a medicine called valtrex . If she cant be seen soon by her primary doctor then go to er or walk in clinic.
Hope she is better soon
