I had the same problem as redraindrop and turned out to be panic attacks.They called it phantom pains and they feel like your having a heart attack but your not its just in your head.Panic attacks are sometimes caused by a stressful or traumatic time in your life that catch up to you later and fuck with your head.What helped me through it is taking deep breaths,talking slow when reading something and ,believe it or not, dancing.Its not the weed its motherfucking dam panic attacks and boy do they suck.
