Welcome again. I saw all the pics.
It seems your father is suffering from carbuncles. It is like an abscess
with opening on the surface draining pus.
In diabetics and immunocompromised persons, such infections are very common.
For the condition, there are number of drugs like augmentin
. But renal modification of doses is required in all, that will depend on the kidney function test.
The dose is decided on the basis of the levels of urea, creatinine
I will advice you to admit your father in a hospital so that correct dosages can be given along with monitoring of the kidney function tests.
Here on XXXXXXX we as doctors cannot monitor the kidney function tests, we can only advice you in right direction.
Your father needs treatment under supervision, as this infection can lead to acute complication on chronic kidney disease
due to sepsis.
If you have any further queries, you may ask me. Else you may close the discussion and rate it.
