In the case of Addison G., treatment for acute hip pain was as follows: 

The culprit was the gluteus medius as I had suspected, but other muscles were involved. All were treated with Neuromuscular Therapy techniques in my greater Boston clinic.

The gluteus medius radiated hot pain all around one specific Trigger Point site. It’s partner, the gluteus minimus, of course had Trigger Points into the side of the hip.

Involved also were the gluteus maximus and the piriformis beneath it with their Trigger Points into the hip and buttock.

The hip flexor called the tensor fascia lata (TFL) had strong referrals right into the hip joint.

The multifidi, deep lumbar paraspinal muscles, and the lumbar portions of the two more superficial erector spinae muscles in the low back were another major source of pain radiating hot pain down into the hip and out to the side waist.

Sustained pressure on the most active and painful Trigger Points, to encourage them to relax and let blood in, produced extreme soreness the next day (like after a hard workout) from the release of the stored waste products that cause pain. Treatment of these same muscles for an hour did the trick. The third day he could move without pain. The same muscles were treated with local and referred pain greatly reduced. He left the office with a spring in his step!
