Dallas,

When you lift your arm above shoulder height, there are tendons that cross in your shoulder. You can feel this or some people even hear a click when lifting their arm above their heads.

If you are still having the pain, you may have damaged one of them. Here is a page you may want to look at:

Tendons heal slowly, they are built like ropes with many small strands and can break. Mercury interferes with vitamin C (which is why mercury toxic persons should be taking vitamin C supplements) which is necessary to make bones, ligaments and tendons strong.

If this pain continues unchanged, you may want to get a doctor to look at it to prevent permanent damage.

In the mean time, there are a couple supplements that can help heal and supress the swelling and pain:

Glucosamine

JNT - Joint Health Supplement

Hope this helps.
