Unexplained Fever and Redness in the Leg: Dermatology Insights

Intermittent fever with redness in the calves during fever episodes?

Hello, doctor.
I have been experiencing intermittent fevers over the past year.
The fever doesn't last long, usually resolving within one or two days.
During the fever, I notice that the area near my right thigh close to the ankle becomes red and the color deepens, and there is a sharp pain when I touch it.
Generally, the color of my right thigh is darker than my left thigh.
Whenever I feel a bit unwell and notice this phenomenon in my right thigh, I know that I am about to have a fever.
Someone told me that this might be due to a bacterial infection in my right thigh, possibly related to the fungus causing my athlete's foot, as my left thigh does not exhibit these symptoms.
I have athlete's foot on my right foot but not on my left.
They suggested that I see a dermatologist, so I am writing to ask whether this falls under dermatological care or if it should be addressed by another specialty.
Additionally, I have a long-standing issue with dark circles under my eyes.
I found a previous Q&A where a doctor suggested purchasing a good quality concealer for the eye area.
Could you please advise where to buy one or if there are any better treatment options? Thank you.

Online diagnosis is not possible; please consult a dermatologist or an infectious disease specialist.

(Not an advertisement) You might want to try Dior's Snow UV SPF 50 whitening spot corrector, but do not apply it too thickly.

More Info

The symptoms you are experiencing, including unexplained fever and redness in your right thigh near the ankle, warrant careful consideration. The combination of intermittent fever and localized skin changes can indicate several underlying conditions, and it is crucial to approach this systematically.

Firstly, the redness and pain in your thigh could suggest a localized infection, such as cellulitis, which is a bacterial skin infection. This is particularly plausible given your mention of having athlete's foot (tinea pedis) on the same side, as fungal infections can sometimes predispose individuals to bacterial infections. The fact that you notice a correlation between the onset of fever and the skin changes further supports the possibility of an infectious process.
Additionally, the darker coloration of your right thigh compared to the left could be due to several factors, including chronic inflammation or venous insufficiency, which can lead to changes in skin pigmentation. If the skin is consistently inflamed or irritated, it may also appear darker over time.
It is essential to consult a dermatologist or a healthcare provider who can perform a thorough examination. They may recommend diagnostic tests, such as blood tests or imaging studies, to rule out any systemic infections or other underlying conditions. If an infection is confirmed, appropriate antibiotic therapy will be necessary.
In terms of management, if you suspect that your athlete's foot is contributing to your symptoms, treating that condition is crucial. Over-the-counter antifungal creams can be effective, but if the infection is severe or persistent, a prescription antifungal may be required.
Regarding your concern about dark circles under your eyes, this is a common issue that can be attributed to various factors, including genetics, lack of sleep, and skin thinning. While concealers can help mask the appearance of dark circles, addressing the underlying causes is essential for long-term improvement. Adequate hydration, a balanced diet, and proper sleep hygiene can contribute positively to the appearance of your skin.
In summary, your symptoms should be evaluated by a healthcare professional to determine the exact cause and appropriate treatment. It is advisable to seek dermatological care for the skin issues and consider lifestyle modifications for the dark circles. Your health and comfort are paramount, and timely intervention can lead to better outcomes.
