Muscle pain in the gluteus minimus is usually related to simple everyday problems, such as sleeping without support, standing for too long, sitting for too long or walking on an uneven surface. It can also be an indication of a more serious problem like sciatic nerve entrapment, SI joint dysfunction, trochanteric bursitis, spinal stenosis or compression of the cauda equina, according to the National Association of Myofascial Trigger Point Therapists. The gluteus minimus is the "abductor of the thigh" and is a member of the buttock muscle group.
Gluteus minimus pain is usually felt on the side or the back of the thigh and can extend downward to the knee or ankle. Most people will also experience hip pain and the pain may be so extreme that the person wakes up from sleeping or feels that they need to sit down immediately when standing, according to Healthline.
For people who are experiencing gluteus minimus pain, there are a few at-home solutions that can be tried before visiting a doctor for treatment, according to the National Association of Myofascial Trigger Point Therapists. These include not sitting or standing in one position for longer than fifteen to twenty minutes and self-massaging the tissue for muscle relief. It is also advised that those who sleep on their back and on their sides, place pillows beneath or between their knees for optimal support.
