I use a small ball in a sock to help my feet, I looked up the top of my feet were black and blue and it said plantar fasciitis, but it shows up in many different ways. Also elevation helps.

I have constant pain in my feet like you, sometimes shooting into my cloves and even in groin area. I use Vicodin when it is awful and also have script for baclofen but don't like to take either 1 too frequently. I would def talk with your neuro. I think very common with ms

I bought one of those foot massagers at the county fair. I've also rubbed Vaporub on my feet and put socks on. I know these aren't medical stuff but it helps me. Good shoe inserts too.

I have a lot of problems with pain and spasms in my legs and feet. Meds help some (lyrica, cymbalta, mirapex). Contrary to the usual advice for MSers, the thing that helps me the most is sitting in the hot tub for just 15min or so right before I go to bed. Eases the pain and spasms and makes me really tired so I can sleep. I know of a few others that are also helped by the hot tub, but it isn't for everyone.

I'm sorry about your feet pain🫣
