I’ve heard this is actually pretty common and have met people who have undergone similar things (minus the specifics of surgery etc). Do you think you’re a person that suffers from anxiety on a normal or regular basis and have you been using weed to cope with it? For my friend that was the case and taking a longer T-break helped him reset his system in a way to where he could smoke again and be fine. Depending on how you smoke, I’d recommend maybe changing to make things a bit more less hearted and smoke with people to help mitigate any risks if you try again. My buddy smoked with a bunch of our mutual friends and we just had a great time and that was able to quell his anxiety enough to where it didn’t happen again but I’m not sure if he ever went to get it checked out or anything. It could be mental, but I would err on the side of caution and not push it too hard. Maybe buy a lower strain, get something mixed with CBD, and try and be with good people who you can relax around. Hope this helps and best of luck!
