What should you know about osteoarthritis and osteomyelitis?

Osteoarthritis commonly causes activity-related joint pain, stiffness, swelling, and reduced range of motion. Symptoms often develop gradually in a knee, hip, hand, or another joint. Morning joint stiffness may occur, especially after being still, but the pattern alone cannot confirm the cause.

Osteomyelitis affects bone and may follow an open injury, surgery, spread from nearby tissue, or another source of infection. It can cause deep pain, warmth, swelling, fever, chills, drainage, or feeling unwell. A painful joint does not by itself indicate osteomyelitis; infection needs a clinician’s assessment and testing.

For suspected osteoarthritis, pacing, suitable strengthening, mobility work, weight-management support, and prescribed pain relief may reduce strain and improve function. A physiotherapist can adapt activity around the affected joint. Anti-inflammatory medication or a cortisone injection may be considered by a clinician after checking risks and the diagnosis.

Suspected osteomyelitis should not be treated with home exercise or leftover antibiotics. Medical care may involve examination, blood tests, imaging, and a targeted treatment plan. Keep any wound clean and follow instructions about dressings and medicines.

Seek urgent medical care for fever with deep bone or joint pain, rapidly worsening swelling or redness, pus or drainage, severe pain after surgery or an open injury, or feeling faint or confused. For non-urgent joint pain, arrange review when symptoms persist, disturb sleep, or limit walking, work, or daily tasks.

Ask which findings support osteoarthritis and which would raise concern for infection, and whether imaging or blood tests are needed. Discuss safe exercise, medication side effects, wound care, and the exact warning signs that should trigger urgent reassessment.
