Is Ice Skating Bad After Acl Surgery Really Bad Blister From Ice Skating?

Really bad blister from ice skating? - is ice skating bad after acl surgery

Just got back from the rink and now I have a huge blister on the back of the heel. What can I do less harm?
Something that can be washed or put it to heal faster
(Application at home is best for me, but I'm open) for suggestions

As in England btw
