@A MyBCTeam Member McGuinn. I had de Quarvain's tendonitis induced by Cipro (surgery). De Quarvain's thyroiditis affects the same tendon with same pain but caused by hypothyroidism or Hashimoto's. Linked to low estrogen of aromatase inhibitors.

De Quervain's tenosynovitis (thumb/wrist tendon pain) isn't directly linked to thyroid issues in the context of breast cancer. However, joint and tendon pain is a well-known side effect of breast cancer treatments, particularly aromatase inhibitors like letrozole, anastrozole, and exemestane.

These medications lower estrogen levels, which can lead to:

- Stiff, sore joints
- Muscle weakness
- Pain in the hands, wrists, knees, hips, and shoulders

This type of pain could feel similar to De Quervain's symptoms. It's worth bringing this up with your care team, as they can help identify whether your treatment may be contributing to the discomfort and suggest ways to manage it.

Thank you Mary. Again, so sorry you have to deal with this. So far my Anastrozole is not affecting me in any real noticeable ways. Take care of yourself and find some relief. 🙏❤️
