Thanks for writing to H.C.M. for your query.
I have gone through your query regarding blocked of ear canal
by dry blood. Since only 5 days are passed only so don't worry about blood crest in the canal this is a normal finding post operated cases. The ear canal is blocked not only by dried blood but it also have pieces of AB GEL which are put over newly formed ear drum.
Actualy there is no need of putting any thing to operated ear without concent of your surgeon. this dried blood and gel foam all will come out in about 10 to 15 days, or it can be removed gentaly by your surgeon in your post operative visits.
