I obtained the reusable hot/cold ice/heat compress gel packs for my husband who suffers from Authritis.
Sometimes his knee becomes very swollen and he limps badly. I use the ice cold compress gel packs (inside a pillowcase) put them on his knee, put a bandage around the packs and leave it on for 15 minutes.
I do this daily until the swelling goes down and he feels much better again.
So, this product is "just what the Doctor ordered" as they say.
Very many thanks.
