I had them in early recovery - first couple of months, they were pretty uncomfortable. I talked about them, stayed focused on prayer and my early attempts at meditation, step work, etc. They improved and disappeared all together.
About a year and a half ago, they came back! They were uncomfortable, but not to the point that I wanted to drink. By that time, I learned how to step back from sensation and act rather than react. I saw a therapist who helped me to expand my meditation repertoire to include routines for easing anxiety.
I don't know if it's normal, PAWS-type stuff, but I know it can be dealt with and it does get better.
Peace & Love,
