My trigger shot (HCG) is tonight at 9:30! I am so nervous! It is pretty scary looking and it goes in the top part of your butt & under your hip bone area. It's 1 1/2" long and I am NOT looking forward to it. But Tuesday morning is my ER so I have to keep my thoughts on that. I too have experienced bloatness and constipation. These are normal to experience. The tingling could be your circualtion......I have it too. From being so bloated I haven't been very active and therefore my circulation hasn't been moving as it normally does.
i became extremley bloated because of a mild case of hypersimulation.... never felt tingling tho..... as for the trigger shot, i gave it to my self in the same area i was giving myself the other shots... (i was doing it in my stomach, but i've heard the thigh is another place to do it)
