I suffer with alot of pain in my legs and feet, specially when ive been on them for awhile. I use Voltarol gel that helps, painrelif helps too plus when ive finished being on my feet, i sit down and put my legs up.
And with the pain in the upper back and shoulder blades, the pain gel and painkillers helps that too. When i get sharp pains in my shoulders and back, i go lay on my bed and dont move if i can it slowly help the pain less, its always there but i can cope with it a bit better.
Also when im in pain i do breathing control that helps too, i breathe in from my nose and out through my mouth, it also does help not thinking about the pain. Just picture urself somewhere u'd like to go and think about what u would like to do or see.
