Casey I can relate to the arm thing, only mine is from computer work. Probably computer work and dragging my bags around the world. It's normally my left shoulder that acts up and boy can it be uncomfortable. That's usually when I go get one of those Thai massages that I love so much if I'm home, or if I'm traveling any massage helps a bit. I use tiger balm as well before I go to sleep to help relax the muscles in there...
Hang in there, amp! Family is tough, but it's such sweet relief when it's over! haha. I love my family but I find anything longer than 10 days is just TOO much with them.
