Brief Answer:
Povidone iodine, pop up, antibiotic and anti-inflammatory.

Detailed Answer:
Hi.
Thanks for your query and a clear picture.
Seen the image which shows a healing wound up and to the right, the one which is very obvious with stretched and discolored skin, and a pointed white spot is cellulitis with pointing abscess.
Due to shear pressure the skin gives the burning and irritating sensation.

I would advise you the following:
Apply liquid povidone iodine locally and try to open up the white dead skin; if done, this will release the pressure and aid in healing.
Addition of an antibiotic and anti-inflammatory can help to reduce the pain further, help in faster healing.
Please continue applying liquid povidone iodine daily so that the further infection is avoided

I hope this answer helps you, please feel free to ask for further relevant queries if you need to or if you feel that there is a gap of communication.
