I’m sorry to hear about your experience.
A bruise (or contusion) is caused by bleeding under the skin which may stimulate surrounding nerve endings and be perceived as pain.
For the bruise, you may use heat application, massage, or topical cream (such as hirudoid) that promotes absorption of the bleeding.
If the pain is severe and dehabilitating, you may need to visit a medical practitioner for oral painkiller and anti-inflammatory.
If you weee to visit a TCM clinic, typical methods such as acupuncture, cupping, tuina massage and herbal medication can be used to enhance circulation, promote absorption of the bleeding and to alleviate your pain and discomfort.
Wishing you a speedy recovery!
Warmest regards,
Physician Lee
