There are many other diseases that could cause these symptoms.(Lyme, pinched nerve, slipped disc...etc) You need to have more tests performed by the dr. Get a neurology consult as soon as you can along with a referral to a Physical Therapist to start working on your physical problems with your right side. Good luck to you!
i know i am of no help, but when i was a teenager, i had the SAME issue. I dont know if its the same reason, but with my issue, i ended up having to have a nerve block in my neck.
Everything i ever had done turned out to be negative, it makes you feel like you dont know what you are talking about, and people think you are making it up. I do hope you find an answer!
