For three weeks, I have had what feels like muscle pain in my right arm, right shoulder, neck, and side. The most pronounced pain is in my arm. There have been time, usually at night, when the pain is upwards of a 9 out of 10. Usually, throughout the day, it is more like a 6. When I use my computer mouse, or lift objects, it gets stronger. I am taking ibuprofen maximum recommended dose, daily (2 capsules, 200mg each, at 6am, 12pm, and 6pm). It seems to help. Your thoughts?
