Knowledge request- not great pics, but this is my arm and hand. My veins in my arms, hands and legs and feet will pop out like this. It's painful. I drink at least a liter of water a day so I'm not thinking its dehydration. Anyone else have this happen? I have #celiac #raynaudsyndrome #mitralvalveprolapsesyndrome #ibs #osteoarthritis and #fibromyalgia Thanks in advance for any help/suggestions!
