Even if slightly hot, or if I go in the sun, it exacerbates all symptoms, and triggers some type of poisoned feeling, prickly sensations in the jaw, and chest, (similar to arachidodnic acid during a heart attack), circulating. It could be compared to when being injected with local anesthetic!! It also increases heart rate, and chaotic sympathetic nervous response I was curious to find out, and stumbled across and article, which describes the above. It discusses the sun/heart increasing free radicals. I lost the article, if someone else has it, could you please post the link?
