I Recently Noticed Weakness In One Or Both Legs When

I recently noticed weakness in one or both legs when walking after having been seated, even after a short period of time. The area in the leg(s) that is weak will vary, and has even made it difficult to bear weight, even to the point that I am frightened. After I am up and about the symptoms go away. I have Mollaret's Meningitis (28 years), and wonder if this could be a neurological complication from it.
