Here I will list a 10 point plan on how to control pain, it's really for ME, but anyone suffering long-term pain, chronic pain, and Gary-J, can use it.
1) Take some time out of your day for peace & quiet. Take 3 seperate moments in your day, and stop, for a few minutes of peace and quiet. Try to think of happy, peaceful times in your past, and let your mind rest there. Then count your blessings.
2) Allow yourself some rest, let go, do nothing. Concentrate on your breathing, long slow deep breaths. Rest is a necessity, not a luxury.
3) Take time to wonder at nature. Watch water flowing, watch the waves crashing to the shore, listen to the birds sing.
4) Set your own pace. If someone is pushing you, to go quicker, it's alright to say "NO". Have some structure in your day. Think about how long you can stand, sit, move about, to perform a task.
5) Talk slower, talk less, or don't talk at all. Listen to what others are saying to you, don't try to think of what you'll say next, it'll come.
6) Don't eat so fast, enjoy your food, it's for pleasure, as well as nourishment.
7) Make time for play. No matter what age you are. The "inner-child" in us all, needs play time too.
8) Exercise. Plan some exercise each day, or every other day. Don't do too much, your body will tell you when you've done enough, listen to it.
9) If you find yourself rushing and anxious, STOP. Ask yourself "WHY?"
10) Get into the moment. Stroke a furry pet ( a dog or a cat perhaps) and talk to it. You will get the gift of NOW. Your breathing will slow, and endorphins will flow.

That was for ME, and anyone in chronic pain. I wish that I could stick to the 10 point plan myself, it ain't easy, even for us raspberry ripples. Cheers...
PS If you Google "Endorphins" there are some sites that will explain ways of letting endorphins flow, or you can just find out what they are, and what they do, Cheers...
