Well as someone who has a bigger problem than you, I say that those minney mouse excerises are the best thing for you. I stretch 2 times a day. On the trail it even more important. I would keep doing all of those and more if you can.
I think sleeping in a hammock will help. You go from only a couple pressure points to your whole body. I feel a lot better in a hammock than on the ground.
Also make sure your pack is light and loaded evenly. It is important too to have it adjusted correctly. I have shoulder pain when it is not sitting right on my shoulders. This is usually done with the load lifting and loosening the shoulder straps.
Is that too much to ask? Girls with frikkin' lasers on their heads?
