Hello
I have studied your case.
As per your history and symptoms possibility of
cellulitis with
dermatitis can be considered on forearm.
Primarily you can take enzyme to decrease swelling like Tab Trypsin and
chymotrypsin.
Consulting your doctor infection /cellulitis can be confirmed, antibiotic can be started according to examination.
If required you may need to do blood investigation for prognosis and recovery.
Colour Doppler study will help to know cause of edema.
Take precaution to avoid spread of infection.
Vitamin B12 is important in the maintenance of health and normal functioning of the
nerve tissue in diabetic patient. You can increase B12 level by taking meat and fish, or you can take Inj methylcobalamine 1500 mcg alternate day. [6 doses]
