Does anybody know if an inner ear problem can occur from concussion or what inner ear issues can carry similar symptoms of PCS? I'm starting to think my problem may inner ear rather than PCS. I'm starting to have some dizziness that I would assume subsides early in the recovery process (concussion was 2 months ago). My ears also pop every time I swallow and tinnitus is present as mentioned in an earlier post. No sensitivity to light/tv/reading
