Cellulitis fluid: swelling, drainage and what it means

Inflammation can make tissue swollen and cause clear or straw-coloured fluid to seep from broken skin. Thick, cloudy or foul-smelling drainage may be pus, which can indicate a pocket of infection rather than cellulitis alone. A blister, soft fluctuant lump or persistent leak needs an examination because antibiotics alone may not address a drainable collection.

Do not assume every wet area is cellulitis: eczema, a wound, friction or another skin condition can also ooze. Type 2 Diabetes, poor circulation or an opening between the toes from Athlete's Foot can alter how a foot infection behaves.

Arrange medical review, especially for pus, an enlarging blister or increasing swelling. Wash hands before and after touching the area, rinse gently with clean water, pat dry and cover with a fresh non-stick dressing. Elevate the limb if comfortable. Do not squeeze, pierce or try to drain it yourself, and do not seal an infected area under an airtight covering.

Seek same-day care for rapidly spreading redness, worsening pain, a new tender lump, red streaks, fever or chills. Go to emergency care for confusion, faintness, breathing difficulty, severe weakness, rapidly worsening swelling or skin that becomes dusky, grey or numb. These signs can indicate a deeper or body-wide infection, including Sepsis.

Ask whether the fluid is expected inflammation, an abscess or another problem, and whether a sample or procedure is needed. Ask how often to change the dressing, how to protect nearby skin, and which changes should bring you back urgently.
