Although mine have not required stents, they do seem to take longer to recover from than when I had my first and was younger. The last one I remember feeling like it was unfortable for about a month and that was without everything you have gone through with yours. So perhaps it is still healing but I think I would be having another chat with my doc just so he is in the loop. Hope you feel better soon.
