Hello, Thanks for your query. The first step in treating a deep thigh bruise is to follow the RICE method. First, immediately stop whatever you were doing when you got the bruise, and apply ice or a cold pack that s wrapped in a towel or cloth to protect the skin to the area. For the first four to six hours immediately following the injury, you should apply ice for about 20 minutes per hour, and then every 3 to 4 waking hours over the next two days. While applying ice, you should bend the knee as far as you can without causing pain to help prevent stiffness and loss of range of motion. If you re not allergic to ibuprofen or acetaminophen, you can take either one of these medications to help with pain and keep inflammation down. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
