I have tight sharp pain in my right side of neck only when I breath in if I lay on my right side it is much worse?

Hmmmmm. perhaps it is a neck muscle spasm. spasms can be very painful; try some moist heat, perhaps some gentle stretching, and gentle massage. Not sure why it is worse when you breath in. As with anything else, if it persists, becomes very severe, or you develop shortness of breath, see your physician.
