New symptom out the blue?

Hi everyone, (diagnosed April 22)
Perhaps I’m over reacting but I thought I would ask your advice.
I have PPMS where I have very reduced walking mobility, pins and needles in legs all the time, the dreaded fatigue, spasms in legs at rest but in the last hour I’ve started feeling pins and needles in my left thumb which won’t go away . I don’t know what I expect peeps to say but wanted to get it off my chest. It has me a little worried.
Thank you

I see you posted a day ago. How is your thumb now? Any improvement?
