tendinitis means "inflammation of the tendon. " therefore technically you can get tendinitis anywhere there's a tendon -- and that includes your shoulder. tendinitis of the shoulder probably is less common than say tendinitis of the elbow. if you're experiencing pain in both shoulders at the same time chances are it's not tendinitis. it would be unusual for tendons in opposite joints to flare up at the same time. bilateral shoulder pain could indicate something else such as muscle spasms across the top of the back or perhaps a herniated disc in the spinal column (though the symptoms from that often are one-sided as well). another possibility for pain in both shoulders simultaneously is osteoarthritis. this definitely could flare up in both joints at the same time. of course i'm not a doctor so these are just examples of the types of things that could possibly cause shoulder pain. if you're having pain in a joint your best bet is to see a medical provider. wishing you well!
