Should i still have pain three days after starting antibiotic treatment for cellulitis by surgical incision on posterior. pain is better but significa?

Cellulitis: Sorry you have had to go through this. Yes it is common to still have pain after having incision of an infected area. However, it is also common practice to have follow up after this procedure to make sure you are improving as this is a significant infection. Call your doctor and get followed up

Call your surgeon: Obviously pain is normal in the area of a surgical incision, particularly if you developed cellulitis. If it doesn't seem like it's getting better on the antibiotics, it is possible that an abscess is forming under the skin. See your surgeon for an exam. May also need to order imaging studies to try to see what's beneath the skin. Hope this helps, and best of luck!

It is possible: It is possible to still bave pain. Although, pain should be improving as well as redness. If pain is getting worse, you may have an abscess which is a pocket of pus that may need to be incised and drained. Your surgeon should be able to assess this.
