I had popping, grinding and catching. Pain moved around-in my shoulder, delt, down my bicep, in my shoulder blade. I, too, thought there was something wrong with the joint and/or rotator cuff. At times, moving my arm after it "caught" was excruciating.
I first saw Dr. Foulke at Salem Clinic, Inland Shores. I saw him because he had an opening the same day I called. He ordered x-rays, an ultrasound and referred me to an orthopedist. I saw Dr. Fan at Hope Orthopedics on State St.. Dr. Fan confirmed what the ultrasound tech told me was a calcium deposit. My deposit was about the size of a fingernail.
I had 2 ultrasounds. The last one was during the procedure. The ultrasounds and procedure were done at SRC- Salem Radiology Consultants on Ryan St., not far from Costco.
