Dysthesia - back or MS or both?

Hi all - I have been diagnosed with RRMS since 2013 but have not had symptoms since dignosis.

In April I was digging in the garden and the next day my hip flexors on the right stopped flexing which calmed down gradually over a week. I was then left with bilateral dysthesia (burning mostly) which has settled on my left leg.

This gets worse when I exercise and/or flexing my lumbar spine (as opposed to neck) - I am just wondering if this is something other folk have experienced? I’m beginning to wonder if I have tweaked my back and have a radiculopathy rather than a MS flare??? Or both!!!

out of interest do you work in the medical field?
