I tried the foam roller again at the gym last night. Just like before: a few times before my core / stability workout, a few times at the end. Honestly, it still hurt like Hades, but not quite so intensely. The improvement is encouraging. In addition, my husband ordered me a couple foam rollers online so I will have them at home and have the convenience of inflicting agony on myself at my “leisure”. Why two rollers? I have no idea. I think perhaps the price was right. Maybe I can juggle them.
