We present a case of a 20-year-old college student who had myositis ossificans traumatica develop after a fraternity hazing. [ncbi.nlm.nih.gov]

• Pain

  The patient was struck repeatedly on both of his thighs while standing at attention, and he presented with bilateral thigh pain and stiffness 6 weeks after the incident. [ncbi.nlm.nih.gov]

  The pain is concentrated along the surface (no deep internal pain) and is tender to the touch but not the same level of pain as when I use the associated muscle. [medhelp.org]

  If MO develops, the graded restoration of flexibility and strength with minimal pain becomes the goal of rehabilitation. [bjsm.bmj.com]

  These symptoms include a noticeable lump or ‘woody’ feeling in the belly of the injured muscle, an increase in morning pain, pain with activity or night pain and a clinical history demonstrating an initial improvement in range of movement followed by [physioadvisor.com.au]

• Swelling

  There may be localized tissue hyperaemia, swelling and tenderness to palpation. [bhj.org.in]

  The patient had a history of trauma due to fall, which resulted in swelling on the left side of his face. The swelling was initially firm, but gradually hardened over a period. [sjmms.net]

  Swelling;-Localised swelling on the anterior thigh or in some cases it may be in the whole limb. [physio-pedia.com]

  Two weeks before the World Championship, after an intense training session, she developed an exuberant swelling on the cubital fossa and brachial region, restricted ROM (loss of 70° on elbow extension), without history of trauma during that session. [bjsm.bmj.com]

• Inflammation

  The patient was treated with physical therapy and indomethacin for pain and inflammation control. At his 1.5-year followup, the patient's left knee flexion had improved to 130 degrees. [ncbi.nlm.nih.gov]

  Initially, after a muscle injury, aggressive stretching should be avoided, as this can increase bleeding or inflammation. [sportsmedtoday.com]

  The inflammation around the joint area gives sharp pain on taking a breath. This can also cause tenderness on pressing the area which pains. An orthopedic doctor can diagnose this for you. Generally there is no cause. [medhelp.org]

  Myositis means inflammation of muscle, and ossificans means bone. A contusion to the arm or thigh causes bleeding, and a clot of blood (hematoma) forms, usually within the muscle. This hematoma then may become bone. [checkorphan.org]

  Biopsies can be performed as a surgical procedure or can be done through a needle inserted into the mass. [verywell.com]

• Weakness

  By the time bone formation has occurred, symptoms may include a palpable lump in the muscle, range of motion that is more restricted than it should be, weakness of the muscle, and ongoing pain. [physiopartners.com]

  The usual presentation is mononeuropathy, pain, variable weakness, and a palpable mass along the nerve distribution. A paucity of literature exists on this disorder. [healio.com]

  In addition, the patient had experienced weakness when biting and chewing, which had endured for more than two years. [spandidos-publications.com]

• Aspiration

  A group of 7 patients with this lesion was treated with hematoma aspiration and injection of steroids, lysosomal enzymes, and xylocaine, resulting in significant limitation of disability. [ncbi.nlm.nih.gov]

• Fracture

  We describe three cases of traumatic myositis ossificans in which fractures occurred through a mature, quiescent ossification mass. None of the fractures reactivated the original pathological process, no callus was formed and union did not occur. [ncbi.nlm.nih.gov]

  Our patient also complained of bilateral numbness to the nasolabial region and cheek.A computed tomography (CT) scan revealed fractures to the nasal bones, associated 1, 2 and 3 Le Fort fractures, right paramedian lower jaw, bilateral zygomatic fractures [jmedicalcasereports.biomedcentral.com]
