it can be a real feeling of being let down when you have a relapse, by your own body! I think having had a relapse that paralysed me temorarily on right side, I tend to look on sensory ones as being let off the hook lightly! But that's not to say every new symptom isin't very upsetting and stressful, I do feel that too, very much.
I have had that burning feeling in the past. It usually lasts a very short time for me, a few days at most. The temp wrong thing is permanant on my right side.
To be honest I try to ignore most tingling/pain/burning/itching up to a point as it comes and goes so much. I think it can vary because of tiredness, temperature, fighting off infections, about 6 weeks after infections or very high stress levels. At the moment I have a feeling like bubbles bursting on my legs, tingling, right sides very mild twitching at night, random itching, and I am trying to ignore the annoyance of it. Grrr!
I once got the burning feeling at the base of my back, down the back of my left leg. I thought, damn and blast, it's moved over to the left side now! It stayed about a week, then I got a rash. Then I realised it wasn't MS this time. It was shingles. It made me laugh that I was so used to ignoring things I hadn't even realised it was a dose of shingles!
Having a CIS - does that mean that the docs don't have you on meds yet? or are they waiting for a while? Will this, as a possible relapse, change that situation for you?
Hope this will pass for you soon, and the feeling goes
