Starting the road to recovery? Along with rest, you will find that one way of reducing pain and swelling is through cold therapy. Wrap an ice pack to the injured knee, ankle, wrist, or painful body part for 10 minutes on and 10 minutes off, to alleviate soreness and muscle pains. If you are always on-the-go, a topical method of pain relief can help; easy to apply. Other methods of rehab can include rebuilding muscle with a muscle stimulator, temporary pain management with a TENS unit, or massaging the muscles with a foam roller.
