Could be bicep tendenitis. Any pain in the shoulder/elbow area? Repetitive exercises can cause it to become inflamed and a sympton is muscle twitching/spasms...try an anti-inflammatory. (I don't mean to hijack...but dont see the need to start a new post) I'm experiencing the same thing with the whooshing noise in my ears. It's been happening on and off for the last couple of weeks...but my BP is normal?? WTF? It's like I'm holding a conch shell up to my ear? Oh well...just thought I'd add that!
