I never know what a questioner means by normal, so I would rather answer that these sensations are not uncommon, and are not a sign of any problem. Every patient has her/his own unique set of sensations after surgery, and their duration varies. Some actually get worse at 2 months as patients begin to resume all pre surgery activities. Almost all of these begin to diminish by 3-4 months, and gradually vanish.
Thank you for your question, best wishes.
