Why is my skin so sore to the touch like my whole body is bruised?

Needs evaluation: You may have systemic infection, collagen vascular disease or other condition which is causing inflammation as when you have the flu and feel achy and sore. Medications have to be considered such as statins which cam affect muscles. See primary care for blood work up if this persists.Also gather all info re meds, o/c medicines, a food diary for several days, work and home environment exposure.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Fibromyalgia is another possibility.
