Hi Thanks for posting your query on HCM. I appreciate your concern for your husband. Apparently he has developed a hematoma on his shin. He needs to be examined by a doctor to check his BP (with high BP there is a high risk of more bleeding) and to rule out fracture, if any. Most hematomas of the shin are best treated at home with 1. Rest 2. Application of ice or cold pack for 20 minutes at a time, 4 - 8 times/day. 3. Compress (Compression can be achieved by using elastic bandages.) 4. Elevate (Elevation of the injured area above the level of the heart ) The pain of a hematoma is usually due to the inflammation surrounding the blood and may be treated with pain medications like Ibuprofen (if he is not taking blood thinner). Ibuprofen is contraindicated because of the high risk of bleeding. Acetaminophen can be a better choice. If hematoma does not resolve, the pressure within it can increase to the point that a “compartment syndrome” can occur. In this situation, the blood supply of the muscle is compromised and the muscle and other structures such as nerves can be permanently damaged. He has to be evaluated by a surgeon for possible surgical drainage of the hematoma. Hope this answers your query. Rate this answer, if you are convinced.
