Welcome to HealthcareMagic forum.
I am sorry for you. Presence of severe pain
with swelling are signs of inflammation. It is important to rule out presence of active infection.
Burn injuries can easily get infected. Bacterial contamination from the surrounding area are the commonest cause. Whilst silver sulfadiazine
is good antiseptic, I feel you need to be on a good antibiotic such as broad spectrum cephalosporin
If I was to be your treating physician, I would suggest you frequent dressing - probably done at a nearest nursing office and put you on a course of antibiotic such as cefotaxime along with a strong antinflammatory analgesic like diclofenac
sodium. I also would like to monitor your blood sugars.
If the healing is not optimal, a plastic surgery
referral is entailed.
Since the healing is not good and you are pain, report back to your treating physician and discuss about the aforementioned options.
Hope this helps.
