Recurrent crossing eyes and new leg and balance problems?

[Musicpiano1]

Hello everyone, I was wondering your thoughts about this? Has anyone experienced problems with crossing eyes in childhood (for me it was age 14) that returned several years later in late 20s? My MRIs are normal and have been assigned for a spinal tap. Since age 14, I have felt daily pain in the back of my head and feels like hard to hold head up. For the past month, I have also been unable to pick up my right leg as if marching up and down. Although I am trying leg exercises and stretches in an attempt to make everything better, it has not gone away yet. I don’t know if this is just due to stress even though my situation is lucky compared to what others experience. I have been referred to neuromuscular disorders department but have not yet received word from the clinic.

Thank you for your kind consideration of this message!
