Can Tymlos cause hip pain?

In November 2022, my husband had a cage with rods and screws put around his spine from his T-9 to his S2, including illiac screws into his pelvis. His neurosurgeon initially said the hip pain that he complained about was caused from the illiac screws and would subside within a year.

At the same time, his neurosurgeon referred him to an endocrinologist, who ran a multitude of tests and determined my husband was pre osteopenia as well as severely low in testosterone. He began Tymlos injections in the spring of 2023, six months post back surgery. He was still having post surgical pain at the time. The endocrinologist prescribed Tymlos 80 mcg (8 clicks). Shortly thereafter, his hip pain began to get worse and is now debilitating.

With his increased hip pain, he contacted his neurosurgeon, who ordered an MRI and other regular xrays of his back and hips. The results showed no diagnostic issues that would be causing such pain.

He was then referred to an orthopedic doctor for hip joint evaluation. While he does have some mild arthritis, the orthopedic doctor said the ball and joint of both hips are in really good condition. He doesn't believe the pain is related to any degeneration in the hip joints. His neurosurgeon is now considering a myleogram as a next step.

With both doctors not being able to determine the cause of his hip pain, I am now questioning his Tymlos as the root cause.

Has anyone else had a similar experience? Since hip pain is not listed as a side effect of Tymlos, how can he safely determine if it is the cause of his pain and how would you go about discussing it with his three doctors? It seems that no one has given thought to his medication as being at the root.
