@snowberry That point between pad and forefinger is LI6 (or Large Intestine 6) and is used for all upper body pain though having said that there are some contraindications with this point and I believe pregnancy is one of them. Also just for interests sake in Acupressure and acupuncture measurement is measured in ‘chun’ (or the width of the finger of the patient on their own body), so for example when i used to practice Chinese medicine and specifically Chinese massage I would have to ‘sight adjust’ if some one was noticeably smaller or larger than I. To do that i would often use LI 6 to get a good view of the patients hand first. Also on a warning note… Pushing this point to hard will just hurt more than help it needs to be pressed in between the fore finger and thumb until felt slightly not till the person winces in pain. As for whats causing the reactions, sneezes and so forth I have no Idea with out seeing somebody in person though yes there are litterally hundreds of points that run throughout the body and at almost every line (meridian) between points there is hundreds of micro points so yes It could be that, truth is could be something completely different to. Interesting though. :-)
