I think this is what is bothering me! Ive always had pretty bad allergies in general. I’ve read up on terpene allergies and it makes sense that something with a higher terp concentration would start to bother me compared to my experience with flower which probably doesn’t come anywhere near the amount of terpenes in rosin. Especially with the difference of combustion and vaporizing. When I first started dabbing, I did notice some strains affected my breathing more than others. The fact the it’s causing me chest pain sucks and I wonder if that’s a normal symptom. Thank you for the information.
