Seek professional care if you experience any of the following symptoms
Generally, Hot swollen red joints can be related to:
Juvenile idiopathic arthritis (JIA) is a type of arthritis that occurs in children under 16 years old. It's a chronic condition characterized by joint pain and swelling that can last for months or years. It affects one or more joints for at least 6 weeks. JIA occurs when the body's immune system attacks its own tissues The cause of JIA is unknown.
Gout and pseudogout are diseases caused by inflammation and crystal accumulation in the joints. Gout results from uric acid crystals, while pseudogout stems from calcium pyrophosphate crystals. Both are marked by sudden, painful swelling in one or more joints. Gout attacks can be triggered by eating purine-rich foods like seafood, alcohol, and red meat, while pseudogout may be due to joint injury, surgery, or immune issues.
A chronic inflammatory disease where the body's immune system attacks multiple joints, most commonly in the hands and feet. The cause and trigger is unknown.
Sometimes, Hot swollen red joints may be related to these serious diseases:
Septic arthritis is an infection of a joint space. This can be caused by a wound that penetrates the joint allowing bacteria to enter, complications following surgery, or by bacteria traveling from distant sites via the bloodstream into the joint.

Q.
Joints Feeling Like Glass? Why Diclofenac Quells the "Internal Fire" & Your Medically-Approved Path to Relief
A.
If your joints feel hot, stiff, and “glassy,” inflammation is likely driving it; diclofenac blocks COX-1 and COX-2 to lower prostaglandins, easing heat, swelling, stiffness, and pain. Topical forms focus relief on a single joint with fewer whole-body risks, while oral versions work bodywide but carry higher stomach, heart, kidney, and liver concerns. There are several factors to consider for a medically approved path to relief, including using the lowest effective dose, avoiding other NSAIDs, and pairing treatment with movement, physical therapy, heat or cold, nutrition, weight management, and monitoring; see details below to guide next steps and to know when urgent care is needed.

Q.
Joints On Fire? Why your body is "rusting" & medical Celecoxib steps
A.
There are several factors to consider. Joint pain that feels like rusting is usually inflammation from osteoarthritis, autoimmune arthritis, gout, overuse, or infection, and chronic inflammation can damage cartilage and limit mobility. Celecoxib, a COX-2 selective NSAID, can ease pain and swelling and may be gentler on the stomach than older NSAIDs, but it carries heart, kidney, blood pressure, and bleeding risks, so use it only with clinician guidance; see below for key safety details, red flags, and the best next steps for your care.
