Little numbness in feet and pain in arms

I started having right arm pain,went to a bone doctor he gave muscle relaxants didnt help.Then I started having numbness, in my right leg on and off,Post that I got diagnosed with covid.I am recovering now,but the previous arm pain has shifted to neck and shoulder and back as well.I am taking muscle relaxants but it is not working,feeling loss of grip in right hand as well.I also have a ganglion cyst.The numbness in my right feet usually comes when I am sitting crossed legged.But it was never present earlier.Also,these shoulder and neck pain had come previous year as well,xray was normal and I got better with muscle relaxants.I am worried are all this symptoms of MS or Spinal tumor.Should I get an Mri done.current medications-maxmala and toperitas d tab.
