Hi, I have studied your case. Traumatic injury can lead to bruise due to hematoma formation. If there is fracture in your thigh bone then it is difficult to walk on it You will need X ray of thigh. Clinical examination is important to rule out thigh ligament injury For these symptoms analgesic and medication can be started. Till time take medication like analgesic and apply crepe bandage over thigh or use supportive splint. Do ice fomentation and rest to leg. Very rarely we need to drain hematoma,usually it resolves gradually on own improving healing process. Take precaution to avoid infection around hematoma. Hope this answers your query.
