A couple days ago I got back from hanging out with friends after quite a stressful day and past two weeks in general. I took a 10mg edible gummy to calm me down and get me ready for bed (something I did the night before and I'm a typical weed smoker daily). What happened about an hour later was something I've never experienced before. 

I had a rapid resting heart rate (100-125 BPM), full body shivers when not covered with a blanket, racing thoughts of doom, neck/back pain, tingling/pins and needles in my left chest and arm, and burning feelings on my back. 

I truly thought I was having a heart attack or something and woke my partner up only to end up staying awake all night until finally tiring myself out at 8am. After about three hours sleep, the next day was filled with a similar feeling of weird symptoms and panic throughout the day. 

Today, I woke up feeling almost completely normal after getting a full 8 hrs and avoiding weed for the day. Fast forward to lunch and dinner time, I experienced similar pins and needles feeling in my chest, nausea, and general anxiety at everything immediately after eating. Additionally, I've started to wonder if these fits are being causes by gastro issues I've had all week (presumably from stress) since they've started to occur after eating. 

Has anything like this happened to anyone else? Ive seemingly never had panic attacks (but commonly have anxiety) before so I don't know what's normal and have been in a googling pit of dispare for the past few days trying to figure out if these are indeed panic attacks or something more serious and the persistent pins and needles in my chest and shoulders has been freaking me out more.
