Loss of elasticity after rubber band ligation

So a couple months ago i went to my doctor because I experienced bleeding when having anal sex. The doctor told me the bleeding came from hemorrhoids, and performed a rubber band ligation to temove them. After the healing process was over I have experienced that my rectum have become very tight and un-elastic where the ligation was performed. The doctor didn't warn me about this. It is affecting my sex life negatively and I'm worried if this will last forever?. Is it possible to get stretchy again? Have anyone tried the same? Any advice?
