Still not full diagnosed but they found lesion on brain and spine 5 years ago. Before I went numb and tingly all over and had some cognitive problems. Few months ago I got really achey arms and legs and that went they done another mri just waiting on the results. My question is… do old symptoms come back? And if they do are they relapses or is it just because of the nerves etc have been damaged so it comes on? From time to time I get pins and needles in feet and hands and my arms ache I don’t know if this is relapsing or just something that will come and go? Currently getting no help on the matter and the dr doesn’t know fa. It’s really frustrating I’m almost hoping they’ll diagnose me with it so at least I can then get some support.
