Anyone have any answers on what to do to reduce the chest pains? I have had severe chest pain constantly for three weeks after taking one naproxen 220mg for neck pain. As my doctor did some may doubt this but I did take two 5 months earlier and same thing happened but only lasting 5 days. Both times when chest pain started I couldn't lift much with left arm for 2 days as it hurt my chest. I have a one year old girl and three year old boy and am only 32. I am scared to death about what could happen. I did see a doctor was only told it will go away and stop taking naproxen. I will be going to the doctors again in the morning.
