Hi,
Thanks for asking.
Based on your query, my opinion is as follows.
1.
Abscess, usually affects and damages large areas, which usually take longer to heal.
2. As the skin closure areas is completely lost, healing from the top, along with formation of granulation tissue (healing tissue) will take time.
3. Improvement with good protein intake, vit C supplements along with avoiding reinfection and controlling of any chronic diseases like
diabetes mellitus is necessary.
4. Get it regularly drained, otherwise abscess can penetrate deep. Watch out for
chills and
rigors to look for blood spread. I assume, he must already be on
oral antibiotics, continue the course and get wound dressing done at regular intervals..
Hope it helps.
Any further queries, happy to help again.
