2 months post Botox…did it fail?

Hi all. Had Botox on 7/25 and felt nearly instant relief. I have had many burps since, but in the last few weeks I have had a hard time burping and am mostly regurgitating or getting silent passes of air (which are great but pretty small). The only way I can get gas to move is drinking carbonation, but sometimes that causes more pain than relief. I feel like my burps have been more like released gurgles, and I don’t feel that same vibration that others seem to, but I’m sure that has to do with the muscle being paralyzed? I’m feeling defeated. I’ve had more bad days than good lately. Is this typical? I am hoping healing isn’t linear in this case and it’s okay to go backwards a little bit.

PS if you’re reading this and debating Botox please don’t think twice - I would get this procedure 15 more times if it meant I could feel the relief I have felt!!
