What could cause a painful, hot, swollen foot in an 80-year-old?

Hello,

Welcome to icliniq.com

I read your query and understand your concern.

It is possible that you could be experiencing a condition called cellulitis. Cellulitis is a bacterial infection that affects the skin and underlying tissues, often resulting in redness, warmth, swelling, and pain. The high levels of CRP (C-reactive protein) in the lab test might indicate an inflammatory response to the infection. While cellulitis can occur in any part of the body, it commonly affects the legs and feet. Since the individual's foot is swollen, painful, hot, and erythematous (red), it aligns with the typical symptoms of cellulitis. It is important to emphasize the significance of seeking medical attention promptly for accurate diagnosis and appropriate treatment. A healthcare professional will assess the individual's symptoms, review their medical history, and order further diagnostic tests, such as blood cultures, to identify the specific bacteria causing the infection. The treatment typically involves antibiotic therapy to eradicate the bacterial infection. Please I encourage the person to consult a physician and start the treatment. I hope I have answered all your queries.

Thank you.
