Ok so iv got a strange one here that I will describe as best as I can... Since yesterday iv had this strange pain on the inside of my wrist were u can see all the veins about an inch below were wrist joins hand. It's like a stinging pain inside whenever I touch wrist almost like there is a big, nasty splinter but there is definitely nothing there as in visible injury and I haven't done anything to wrist for it to have an injury. I feel like my hand and forearm is starting to ache and feel abit odd.. As this is my left wrist/hand I am starting to worry I am having the prelude to a heart attack especially since past few weeks the palpitations have returned along with tiredness and light headedness. Just feel so down with it all and scared.
