A friend of mine in Iraq is having some symptoms which concern me. He has lower back pain, trouble sleeping, muscle twitches in one arm and eyelid twitching and frequent urination.
He is in a very stressful situation. Could this be stress or something medical? he wears a heavy (bullet proof for lack of a better work) jacket on a daily basis and his back hurts constantly.
He also works out a lot and takes some protien supplements.
If anyone has any ideas about this I would appreciate the input.
