I went to the doctor today and turns out I have some sort of muscle spasms in my neck and upper back. It's not at all serious but will be quite painful for the next two weeks during which whatever the hell is wrong, is automatically healed by my body. I'm taking some non-drowsy muscle relaxant and other than the constant pain, should be fully functional. Just like every other time I've been sick, it's nothing serious thankfully, just really really annoying. No kayaking, running, or lifting heavy objects for the next two weeks.
