Reiter's disease is a rare autoimmune disorder that is also known as reactive arthritis. The condition causes inflammation in the joints, eyes, and genitals, leading to pain, swelling, and discomfort. Moreover, this disease can cause skin rashes and sores in the mouth, nose, and eyes, making it difficult for patients to perform everyday activities. Although there are no permanent cures for Reiter's disease, its symptoms can be managed through medications, physiotherapy, and lifestyle modifications. Some other synonyms for Reiter's disease include Reiter syndrome, arthritis urethritica, and post-infectious arthritis. Regardless of the name, it is essential to seek medical attention immediately if experiencing symptoms that match the disorder's characteristics.
