HI there, I am 62 and still dance ballet. The past few weeks when I point my toe (right foot ) I get sharp needle pricking pain in toe. When I touch my toe, part of it feels numb.I also just got back on a plane, can that make you dizzy ? When I put my head down and then up straight I feel very dizzy. ALso when I wash hair and hold my head backwards and then put my head straight, I had to catch myself for falling. I do have issues with ear infections. Can airplane rides cause that ? Thank you for any info. you can give me.
