Hi @jorsech, and welcome to Mayo Clinic Connect. I think it's great that you are seeking the experience of others who have gone through Transcranial magnetic stimulation. You will notice that I moved your post to a discussion where people are talking about TMS already. I did this so that you can connect with those other members about what the doctor wants to do on your next treatment and see if anyone else has experienced that.

You might be interested in reading this article on the the right vs the left side treatment:

Did your doctor mention anything else about right side treatment? Are there any side effects at all?
