You are having severe oedema on feet, legs and hands.
Oaedema caused bullae.
Bullae ruptured at some places leading to erosins with secondary infection.
The cause of oedema should be found out.
For that you consult either physician or nephrologist
Elevation of affected parts, antibiotics,diuretics, anti inflammatory drugs, local application of antibiotic cream..etc would be helpful.
I hope you got my answer.
