I am having chest wall pain. It started at night around 2:00 am. This morning I had to go to the emergency room and the doctor said the I can take a pain reliever such as ibuprofen. I took myloxicam in the morning which gave me some relief. However my pain has started again and I am worried about night time as I could not sleep yesterday night at all. What can I do for the night? Tomorrow morning I will see my own doctor.
