I've just started experiencing heaviness and burning in both legs. I'm assuming it has to do with my MS. I was dx'd 5 years ago after some visual and hearing problems. To date I haven't had any spinal lesions on my MRI - perhaps that is changing

Does anyone else have this symptom and if so how to they manage it? I'm going away on a very special vacation to Key West in two weeks and am just praying this is a fleeting symptom. I'm feeling very afraid for the first time in a few years with this illness.
Thanks for your advice/experiences
