 [ Symptoms ] can you get tendinitis in your shoulders [ Disease ] tendinitis means inflammation of the tendon  therefore technically you can get tendinitis anywhere there is a tendon    and that includes your shoulder tendinitis of the shoulder probably is less common than say tendinitis of the elbow if you are experiencing pain in both shoulders at the same time chances are it is 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 am not a doctor so these are just examples of the types of things that could possibly cause shoulder pain if you are having pain in a joint your best bet is to see a medical provider wishing you well
