Yes, hyperthyroidism can indeed cause skin to itch and feel as if it is crawling, particularly around the neck and scalp. Various resources indicate that both hyperthyroidism and hypothyroidism can lead to significant skin changes associated with itchiness. Common symptoms include dryness, patches of thick, scaly skin, and irritation.

One particular source highlights that pruritus, or itching, is a lesser-known symptom associated with hyperthyroidism, especially in cases of autoimmune disorders such as Graves' disease. This suggests that if someone is experiencing itchy sensations, especially in specific areas like the neck and scalp, it could potentially be linked to hyperthyroid conditions.

The signs and symptoms include not only itchy skin but can also manifest as changes in skin pigmentation and rashes. For instance, general irritations might lead to conditions such as hives or rashes as a manifestation of hyperthyroidism. Furthermore, some individuals may experience clammy skin and general skin irritation.

If these symptoms are present, it may be advisable to consult a healthcare professional for evaluation and potential diagnosis.
