Causes of Joint Pain: Tendinitis, Psoriatic Arthritis, Lyme Disease, Long COVID, Hypothyroidism

Joint pain is a common complaint that can be caused by a variety of conditions beyond just arthritis. From tendinitis to Lyme disease, there are several other factors that can contribute to discomfort in your joints.

One such condition is tendinitis, which is characterized by inflammation or irritation of a tendon. This can lead to pain and tenderness around the joint, with common areas being the shoulders, elbows, wrists, knees, and heels. Age is a primary risk factor for tendinitis, as tendons become less flexible as you get older.

Psoriatic arthritis is another condition that can cause joint pain, particularly in individuals who have psoriasis. This chronic skin disease can lead to symptoms such as joint pain, stiffness, and swelling on both sides of the body. Swollen fingers and toes, pitted nails, and lower back pain are also warning signs of psoriatic arthritis.

Lyme disease, a tick-borne illness, can also result in joint pain as it progresses. While early symptoms may include fever, headaches, fatigue, and a skin rash, joint pain in the knees is a common sign of Lyme arthritis. If left untreated, permanent damage to the joint can occur.

Additionally, individuals who have recovered from COVID-19 may experience joint pain as a symptom of long COVID. Research from the CDC has shown that joint pain is a common complaint among those who continue to experience symptoms weeks or months after their initial infection.

Hypothyroidism, a condition in which the thyroid gland does not produce enough hormones, can also lead to joint pain, stiffness, and swelling. This condition primarily affects middle-aged and older women, though anyone can develop it.

If you are experiencing joint pain, it is important to speak with your doctor to determine the underlying cause and develop a treatment plan. By addressing the root of the issue, you can find relief and improve your overall quality of life.
