Hi, I have been having pains in my arms, hands, legs , and ankles. With that said my veins have been swollen and it seems the pain is coming from my veins. I also feel fluttering on the left side of my chest, I am not sure if that is related at all with my pain. My vein in my ankle got so swollen and I was in so much pain it led me to Urgent Care . The doctor gave me naprosyn which kinda helped. I am also 18 years old and I shouldn't be having this much pain.
