Hi, thanks for writing to HCM. A dent felt in the substance of a muscle indicates tear/rupture of the muscle resulting in hematoma (blood clot), which will be tender to touch. An MRI scan of the involved area is necessary to estimate the extent of the injury to the soft tissues. The general treatment guidelines for your condition are as follows - - Take Rest and do not do any activities that cause pain till the acute pain subsides - Apply ice or a cold pack to the painful area for 15 to 20 minutes, 4 times a day for several days. Wrap the ice or cold pack in a towel. Do not apply the ice directly to your skin. - Take ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) to help relieve pain - Use moist heat fomentation when you are returning to physical activity. Then use it before stretching. Gentle heating can help loosen the muscle - Gentle massaging of the painful area with a painkiller cream may provide swift relief - When the acute pain is gone, start gentle stretching exercises. Stay within pain limits. Hold each stretch for about 10 seconds and repeat 6 times. - Physical therapy may speed up the recovery process. Therapeutic modalities such as Ultrasound, Massaging and specific exercises will be helpful. Consult an orthopedic surgeon for further evaluation and definitive management. Hope this information is helpful. Good day
