I had terrible fever nausea and chills, the next day i was diagnosed with quickly spreading cellulitis on my leg. my headache and fever has subsided but it's still painful to walk, should i worry?

Taking antibiotics?: When diagnosed with cellulitis the most important thing is to take antibiotics as prescribed to resolve the infection. There may be pain related to injury to tissues on the leg. Headaches and chills were likely as a result of infection. Continue antibiotics and watch for signs of worsening cellulitis like worsening erythema or redness, warmth to touch and fever again.

Iimprovement: If the cellulitis is subsiding as well you are likely going in the right direction. Elevation should help along with warm soaks.

Yes: A cellulitis can lead to sepsis or osteomyelitis if untreated with antibiotics (sometimes IV abx are needed). Usually pain means persistent infection. May want to have doc look at it.

Of course: Probably not a concern and is related to the edema caused by the cellulitis. Need to make sure there is no clot within the arterial or venous system of the involved extremity. Also need to make sure there is no abscess cavity that needs to be drained.

What's the cause ?: Cellulitis is basically a visible inflammation (itis) of the skin and soft tissues (red, hot, swollen and tender) . It can be caused by many things including sunburn (radiation), trauma (sprained ankle) or poor vein circulation (stasis dermatitis). It need not be caused by bacteria. If you have repeated episodes of this, get to a wound care or vascular specialist, the diagnoses you have is wrong.
