The pain when pressing the bone in front of the calf may be related to calf trauma, periostitis, infection, tumor and other reasons. 1. Calf trauma: trauma to the calf will cause local soft tissue damage, and in serious cases, fractures such as middle tibia fracture will occur, which will cause tissue swelling and pain, and the pain will be significantly aggravated when pressed. 2. Osteochondritis Dissecans: If you often participate in long-distance running or mountain climbing and other high-intensity sports, the periosteum between the tibia and fibula of the calf will be continuously and repeatedly pulled, which will form a periosteal tear and lead to osteochondritis dissecans, resulting in congestion and swelling, and there will be obvious pressure and pain when you press it. 3. Infection: When bacterial or tuberculous infection occurs in the soft tissue of the calf and tibia, obvious pain will appear when pressing the calf. 4. Tumor: Tumor occurs in the shin bone of the calf, such as osteosarcoma, osteochondroma, etc., which will cause pain when pressed. If the pain occurs when pressing the bone in front of the calf, it is recommended that the patient go to the hospital to improve the examination and receive regular treatment.
