why pain in right shoulders?
when i feel over worked or get upset and fustrated i get a pain in my right shoulder its feels very tight why would this be?? stress maybe?

Right Shoulder corresponds to the cervical plexus' right aspect which maintains and nourishes that area.

In yogic philosophy, the right cervical plexus (Right Vishuddhi Chakra) represents the center of sweetness and diplomacy. If you look at it from a yogic point of view, it is a manifestation of a blockage of the R. Vishuddhi. To confirm or deny take a short test. Do these additional malfunctions related to the right cervical plexus manifest:

1. Anger, use of sharp words.
2. Inability to handle pressure situations diplomatically.
3. Headache in the left part of the head/forehead.
4. Issues with the liver.
5. Heartburn/Constipation.

If some of the above manifest, then it might be a problem in the subtle system.

the solution is chakra cleansing and kundalini awakening is one good way to do it. Where could you learn it? There is possibly a free class closeby if you would care to look up on the Sahaja Meditation Class directory or elsewhere online.
