I too suffer with unexplained aching, not so much pain, but aching from head to toe. I had viruses three times over the winter and learned from my rheumy that there is a post-viral muscle pain that people can experience.
The first time I had the virus it would not let up and Tramadol would not help. I can't take Prednisone so I started MTX. That helped, but I was taking the pill form and it did a number on my gastro intestinal system. I'm suppose to start injectable MTX soon, but am balking because my recent bloodwork was so good.
Studies have shown that meditation can be a powerful pain reliever. I'm not good at it, but do practice moments of silence and rest more than I used to, that does help.
