Hi I have pretty serious question, the passed few days I ve been in a little pain with my upper left leg around where the hamstring is. I m not sure where this came from but it feels like a Charlie horse. It s now moved up to my thigh area and I m getting small pains in my chest as well as dehydration. I happened to tense up while having intercourse but I m not sure if that s related. I m getting major anxiety thinking about blood clots but am unsure. Also when I lay on my side I get tingly feelings in my feet.
