HI Forumuser and welcome! Congratulations on quitting smoking! I wish I had done it at your age! You have a life time smokefree ahead of you!
Now stop all that worry and make an appointment with you doctor or clinic, ok? There is no reason to start worrying until there is something to worry about! It is probably nothing but you need to get it checked out. Keep us posted, ok? We care!
God bless
