I was put on the combined contraceptive pill permanently this means I don’t have periods at all which has definitely helped. When I used to get what I called the white hot pain I used to get my husband to sit on my back while I lent over a stool.. bit odd but it helped so then I got a curved piece of wood to simulate the same effect when I was sitting working, basically every time the pain hit I would press hard into the wood against my chair and it would have the same feeling. Also coq10 enzyme (boots) helps with energy to cope with the pain and fatigue
