9. Excessive Skin Dryness
The functioning of the skin is controlled by hormones released by the thyroid gland, and hence any problem in the thyroid can cause skin problems.
When the thyroid hormone levels are low, the skin becomes dry and pale. Other symptoms of hypothyroidism include scaly and wrinkled skin, less sweating, change in skin color, edema, brittle and thick nails, and eczema. In the case of an overactive thyroid, the skin tends to become sweaty and itchy.
10. Muscle and Joint Pain
Unexplained aches and pains in the muscles and joints, and a general feeling of weakness in the arms and legs, can all be symptoms of undiagnosed thyroid problems like hypothyroidism and hyperthyroidism.
Underactive thyroid can cause general muscle weakness and pain, including cramps and stiffness. It can also cause general joint pain and contribute to tendonitis in the arms and legs, carpal tunnel syndrome and tarsal tunnel syndrome. All these symptoms can indicate hypothyroidism.
On the other hand, an overactive thyroid or hyperthyroidism may cause muscle weakness and fatigue that may make it difficult to climb stairs, hold objects in your hands and reach your arms above your head.
If you one or more of these symptoms and signs, you may be suffering from an overactive or underactive thyroid condition. Plus, if you have a close family relative who has a thyroid problem, you have a higher risk of having thyroid problems down the road.
