Cellulitis begins when bacteria that normally live harmlessly on the skin’s surface get past that barrier and into deeper tissue. This usually happens through a visible break in the skin, such as a cut, scrape, surgical wound, insect bite, or a crack between the toes from athlete’s foot, though sometimes no obvious entry point is ever found. Skin conditions that damage the surface barrier also raise the risk, and treating \u6e7f\u75b9\u5bfc\u81f4\u7684\u76ae\u80a4\u5c4f\u969c\u53d7\u635f<\/a> \u6216\u6162\u6027\u817f\u90e8\u6e83\u75a1\u8fdb\u884c\u53ca\u65f6\u5904\u7406\uff0c\u6709\u52a9\u4e8e\u6d88\u9664\u7ec6\u83cc\u5165\u4fb5\u7684\u5e38\u89c1\u9014\u5f84\u4e4b\u4e00\u3002<\/p>\n

Cellulitis is diagnosed by a clinician’s exam and the story of how the skin changed, since no single blood test or scan confirms it. That gap is part of why cellulitis is one of the more commonly misdiagnosed skin conditions: research suggests that roughly a third or more of suspected lower-leg cellulitis turns out to be something else on closer review, most often a look-alike condition called stasis dermatitis, and treating a mimic with antibiotics only delays the right care. One of the most useful clues is also one of the simplest: true cellulitis is nearly always unilateral and painful, while its common mimics tend to be bilateral and itchy. Clinicians also work to exclude \u53ef\u5f15\u8d77\u7c7b\u4f3c\u5355\u4fa7\u817f\u90e8\u80bf\u80c0\u7684\u6df1\u9759\u8109\u8840\u6813<\/a>\uff0c\u56e0\u4e3a\u4e24\u8005\u5916\u89c2\u76f8\u4f3c\uff0c\u4f46\u6cbb\u7597\u65b9\u5f0f\u622a\u7136\u4e0d\u540c\u3002<\/p>\n\n

Because cellulitis can return, long-term care often shifts toward prevention once the infection has healed. People with lymphedema or chronic leg swelling face particular risk of repeat episodes, so managing that swelling with compression therapy, keeping skin moisturized, and promptly treating athlete’s foot or other minor skin breaks all help. Compression and swelling management now rank alongside antibiotics in importance, and for frequent episodes, a clinician may also discuss long-term low-dose antibiotics as further protection.<\/p>\n\n

Cellulitis is a bacterial infection of the deeper layers of skin, usually caused by group A strep or staph bacteria, including MRSA, entering through a break in the skin such as a cut, scrape, or crack from athlete’s foot. It most often appears as a red, warm, swollen, and tender area on the lower leg.<\/p>\n

The clearest clue is the pattern: cellulitis is almost always one-sided and painful, while its most common mimic, stasis dermatitis, is usually on both legs and itchy rather than painful. Deep vein thrombosis also tends to be one-sided but causes more swelling and aching than redness, and gout causes sudden, severe pain centered on a single joint rather than spreading across the skin. Because these conditions can look similar at a glance, a clinician’s exam is the best way to sort them out.<\/p>\n

Yes, cellulitis can recur, especially in people with lymphedema, chronic leg swelling, or a previous episode. Managing swelling with compression, keeping skin moisturized, promptly treating athlete’s foot or other skin breaks, and, for frequent recurrences, discussing long-term low-dose antibiotics with a clinician are the main strategies for lowering the risk of another episode.<\/p>\n\n
