Here is My Question:
Can a relapse involving mostly paresthesia in a limb last 6 months and then be gone? Some numbness, motor involvement, ie. dropfoot, and overlay of Uhthoff's - ie symptoms amplified by heat? Then completely gone, except with heat, after 6 months? Couls this be considered a relapse?
It is unlikely that a relapse would last this long. A relapse represents inflammation in the central nervous system. The typical relapse will result in inflammation for <4 weeks (usually not more than 6 weeks). However, once the inflammation ends, a residual scar is left behind which can result in fluctuating symptoms just like you describe. Heat is a common factor that can trigger or worsen those symptoms.
