Hi there Monak84. Although there is some tendonitis in the biceps tendon we must be able to account for why this would be the case if we want to suggest that it is actually the cause of the pain. And overactive upper trapezius suggests this is not this issue and that this finding might well be secondary at best.
I would look at possible accessory mm activity and an elevated first rib. Release the subscapularis under the axilla, perhaps mobilise the AC joint through and at end of range and generally check the movement of the scapula on the thoracic spine. This is most important for any should problem that you find. A tight, kyphotic thoracic spine that cannot extend will always lead to shoulder issues. But remember the symptom is not necessarily the casue. Look for the "Sign".
Let us know what you find. p.s. Today we will enable uploading of file along with posts to this system. We will restrict the size of the attachements but this will permit uploading of image files such as x-rays and also clinical protocols and guidelines
