I am a 62 Yr Old Female who experiences the same type pain! I like you, take very little Meds! Diabetic Type 2 arthritis, & Fibromyalgia as well as Chronic Mono! So I have exerted myself to malaise in going to doctors, NPH's, to ER. Still nothing after extensive checks other than the Mono flare, and some Degenerative Joints including my back. The med that has helped me is Flexeril. I was finally told I have COSTOCHRONDRITIS. Now mind you. That's a mouthful. Research it as well as bloodworm! Good Luck! Mississippi Raine
