Why can't I use ThermaCare® on areas with bruising or swelling?

Heat may aggravate the injury if used on areas of swelling or bruising. Physicians and pharmacists generally recommend using ice periodically in the first 24–48 hours for injuries that can cause bruising or swelling. However, after 48 hours, heat such as that provided by ThermaCare® has been found to effectively provide pain relief. Consult your doctor or pharmacist for more information.
