I use Voltaren gel to help with the aches and pains its so much better than the A535 stuff, and I alternate my time between piecing and sewing I don't do either activity for more than 20 mins and I take breaks in between. Even if I go to class at the LQS my instructor will tap me on the shoulder and say shouldn't you switch up. She knows I have a lot of major issues with my back and my shoulders. A friend had me try their Bio Freeze over the holidays and that works very fast as well to relieve the aches and pains, she's got Osteo Arthritis of the spine and dealing with a frozen shoulder as well.
