Yes, also diagnosed with Gluteal Tendinopathy which orthopedic thought for a long time was Burtitis in the hip. I have also tried acupuncture, dry needling, myofascial trigger massage, regular massage, red light therapy, grounding sheet, PT, stretch labs, etc. Agree on reading about low estrogen can debilitate the tendons. I find most of my tendons throughout my body are not like they used to be and hurt repeatedly. TMJ, shoulder blades, ankles, knees, hips and low back. MRI's show mild arthritis but doesn't seem enough to cause this much pain. It doesn't take much to aggravate any one of them and be out for days. I am not one to think about HRT because of its possible cardiovascular and cancer risks but I am almost there to try it.
