My right hand seems to be slowly swelling finger tips feel fuller, hand feels a bit heavy, some mild tingling and a bit of a throbbing sensation, also a noticeable difference in the size of my right hand compared to the left. This is some 18 hours after receiving an electric shock from a low voltage lamp, I accidently touched the exposed wires. Is there any cause for concern, as I am keeping an eye on my breathing as I felt slightly breathless after the initial shock.
