ouch...that looks awful..use aloe on it
last week I was pressing a quilt w/ steam and suddenly My iron started leaking boiling hot water..I have problems with my legs so I was sitting and my legs were under the ironing board...my thighs and a little of my belly got burned and at first it stung bad...I keep a bottle of 100% aloe gel in the refrigerator (keeping it cold just feels good on the burns) for whenever anyone gets burned a bottle costs about $7-8 but will last a long long time in the fridge.... I put the aloe gel on it right away...no blistering nothing it just got red and the next day it was almost gone I used aloe on it several times the first two days and it is gone and never did hurt after that....
Hope it heals up fast
