My injury was on a Tuesday Afternoon.,
That thursday afternoon I notice symptoms, went to ER.
Friday I took off work, slept half the day, felt better.
Saturday I hung around the house and was lazy, was feeling better.
Sunday morning I felt normal, expected to be going back to work Monday.
Sunday night, the muscle in the back of my head and neck swelled up, my symptoms came back 10 times worse, and I have yet to realize a major improvement that does not come from medicine. That was 3 months ago.
also, on that Sunday night, I popped a lymph node in my neck; no dr. can tell me why that happened.

So, I got better then got worse, in a matter of a weekend.
