Hi, I have stinging, tightness, redness and electrical shock type of sensations in my left palm below my thumb as well as the palm area below my index and middle finger. The shock feeling is at the tip of my index finger and tip and down my thumb. Also, when I look at the palm area below my thumb and the area below the index & middle finger, it seems as if my veins are more pronounced. At times, there is a burning pain along the side pinky finger and this pain runs down the side of my palm. None of the pain I experienced reaches my wrist . This has been occuring off and on for at least 6-8 months.
