Hi Mick! Welcome!
I have lesions between T4 and T9. My 1st major attack took about a year to get most of the function back in my left leg. 3 years later, I still have weakness in both legs but only if I over do it and coordination issues and sensory issues - these may be more related to brain lesions than spinal. I now know I will always have this and it is permanent.
Similar to Lady Express, it takes me a good 4 to 8 weeks to start feeling better after a spinal flare. There is not much you can do but rest and wait it out.
Give yourself some time. I hope you start feeling better soon.

Check in and let us know how you are doing.
