Hi, I feel your pain. I had these a lot some years ago.
The standard exercise for runners is the pot-of-paint-hooked-around-ankle exercise. Hang a weight off your foot at the ankle like a pot of paint while seated. Lift leg slowly up and down by extending and dropping it. DO for 1 min, do other side, repeat a few times.
Wear cushioning shoes and do as little running and impact exercise as possible. You can retain aerobic fitness by swimming or biking.
As said above, ibuprofen helps.
"running them off" doesn't work. They come back worse, each time. I finally did no sports at all for 2 months and they haven't come back since.
Make sure when you start back running you have the right shoes.
