So I’m in my early 20s and don’t feel like I am honestly. I went walking in the heat and after my ankles started to feel tight and my hands and face was tingling as well as hand tightness. My muscle feel extremely weak and I have this pain on my left side of my breast and my chest feels like a lot of pressure. I’m not overweight and I walk alot but I can’t tolerate the heat at all for my age and it cuts into my lifestyle! What to do?
