I get lumps under my skin on my arms, and I have at least one on my back.
I believe they're called ganglion cysts.

Hi Serenity- let me send a belated welcome to you. I'm glad to see you have stuck around - this really is a great place to learn more about MS and to just hang out to fill time.
I'm not sure I really understand what kind of lumps you are feeling. Lumps generally would not be associated with MS because it is a disease of the central nervous system.
By any chance, are you on any injections for your MS and if so, are the lumps close to your injection spots? People do sometimes have that type of problem.
welcome again and I'll watch for your reply.
be well, Lulu
