Today I'll talk about how we handled cold and warm compresses. Many vets (and human doctors) recommend using a pack of frozen peas for an ice pack. I put some ice in a freezer bag and reused the same pack. I don't like to waste food and I won't eat peas that have partially thawed and frozen repeatedly. I always wrap the bag of ice in a medium-sized towel. When ice is applied directly to the skin, it can cause nerve and tissue damage. Wrapping the ice helps to prevent that. Leave the pack on for five to ten minutes. Cold compresses are usually used for about three days but follow your vets instructions.
It is important that you do not use boiling water and that you do not heat the damp or wet towel in a microwave. Heated water or towels from the microwave will burn your dog. Do not use anything except warm tap water. Test the temperature on the inside of your wrist like you would a baby bottle.
Of course, I am only a pet owner. If your vet gives your any instructions that contradict mine, you must follow your veterinarian's instructions.
Don't be surprised if the warm compress helps draw out fluids. That's part of of the reason for a warm compresses. It also helps relax the muscle, which promotes healing. Some vets will recommend that you do passive range of motion after or during a warm compress. This is a case-by-case basis so carefully do as your vet recommends.
