Glad you're feeling better, nawchem! On March 25 I sprained my calf muscle just crossing the street. I couldn't put weight on it except to hobble and needed to stay off of it for a couple of weeks. Sitting around caused my back to start hurting, so as my leg got better my back got worse. I was pretty miserable. I am back to feeling 100%. Here's what helped me the most along the way:

1. Rest. Fetal position, knees toward chin feels good.
2. Heating pad.
3. Extra Strength Tylenol.
4. Water, water, water!
5. Bending and stretching to alleviate pain and increase range of motion as I healed.

I also take magnesium citrate daily since starting low carb. It does a world of good in staving off cramps and helping me relax and sleep.

While you're standing there working, be conscious about changing positions and shifting your weight periodically. Try your best to unbend your neck and stand up as straight as you can for a few seconds at a time. I think that may help.

Keep feeling better!
