Swelling in both legs plus a painful swollen hand joint needs an in-person medical assessment soon, preferably today or within 24 hours. It can be due to joint inflammation such as rheumatoid arthritis, but leg swelling can also come from kidney, heart, liver, vein, medication, thyroid, or other medical problems. A painful swollen joint can occasionally be an infection and should not be ignored.
Go to emergency care now if she has any of these:
- Shortness of breath, chest pain, fainting, coughing blood, or rapid heartbeat
- Fever, chills, or feeling very unwell
- The hand joint is red, hot, extremely painful, or difficult to move
- One leg becomes much more swollen, red, warm, or painful than the other
- Swelling appeared suddenly or is worsening quickly
The
NHS guidance on leg swelling lists heart, kidney, liver problems, blood clot, and infection among possible causes. A hot, swollen painful joint with fever or malaise requires urgent evaluation because it can indicate joint infection, as noted in
NHS joint-pain guidance.
Until she is seen:
- Rest and elevate the legs when sitting or lying down.
- Avoid massage or tight compression bandages until a clinician excludes a blood clot or circulation problem.
- Do not start steroids or strong pain medicines without medical advice.
- If she can safely take it, paracetamol/acetaminophen may help pain. Avoid ibuprofen, diclofenac, or naproxen until a clinician reviews her, especially if she has kidney disease, stomach ulcers, is pregnant, takes blood thinners, or has heart failure.
A clinician may need to check blood pressure, urine, kidney/liver/thyroid blood tests, inflammation markers, rheumatoid arthritis tests, and possibly heart or vein tests. Joint swelling is a sign of active inflammation or excess fluid within/around the joint (Goldman-Cecil Medicine, physical examination section).
