Many
commercial products are available that can be
micro waved, boiled or chemically activated or electrically
powered to
heat up and provide heat for
comfort or
therapeutically. Some are
moist, some are
dry.
If the heat is "moist" it is thought to penetrate deeper
and be more effective for pain relief.
There is a homemade alternative, a "rice sock". Take a
clean tube sock. Fill it about 2/3 full of regular rice
(not Minute Rice). Sew the end shut (or knot it) leaving
some free space for the rice to spread out.
Heat the rice sock in the microwave about 60 - 90 seconds
per cup of rice. Apply to the painful area for up to 20
minutes at a time. Rice absorbs moisture and then gives it
off when the sock is heated.
Caution, these can burn! Heat varies with microwaves and
with amount rice and humidity. Be careful. Shake the rice
around in inside before applying to skin and if too hot
cover it first.
They will release heat over a 10 - 20 minute period.
This type of moist heat is very good for menstrual cramps,
afterbirth pains, and somewhat helpful for labor pain.
Also great for cold feet!
Pain from an injury is best treated by ice packs (covered
and only 20" on per hour). Heat can feel good but make an injury worse.
