So I was able to hit the weights last night no problem. I took it easy first, starting with a dumbbell flat bench, and slowly ramped myself back up to my usual weight. The headaches were definitely upper trap related, because I could feel my body trying to favor itself up by the neck. I made sure to keep solid form and not cheat with my traps at all. I was able to make it through the entire workout unhinged. Man I feel good today. I think I was actually starting to get depressed about not working out
