Can parathyroid adenoma cause a stiff neck?

Parathyroid adenoma itself typically does not directly cause a stiff neck. However, elevated levels of parathyroid hormone (PTH) due to the adenoma can lead to increased calcium levels in the blood, which might contribute to muscle stiffness or tension. Additionally, if a patient experiences complications related to hypercalcemia, such as dehydration or kidney issues, these could indirectly lead to neck discomfort. It's advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
