I did this at one point in my earlier career. My resume had a job change every 9 - 18 months. I was mortified to find that I was really unhappy at a new place after 5 weeks. I was discussing with my old coworker who let my manager know I was unhappy so they offered to have me back, which I did, but the reasons I left were unresolved some 6 months later so I left again. This time I did some soul searching about what would make me happy. I knew the problem was really with me and though I had strong urges to leave, similar to my previous urges, I managed to stay at my new job for 6 years. The takeaways from my sample size of 1: You can go back. If you left for some particular reason, it is possible that the situation remains unchanged and you will still be unhappy. If you leave again, you will likely burn bridges so be sure you want to be back. If you are doing this on a frequent basis, look within to understand why you have the need to change jobs so often.
