question: hello my name is simon.. i,m 31, 6 foot 1 inch and 13 stone two days ago at work while welding the copper coated welding wire pierced the palm of my hand. My hand has obviously been sore since. last night and today hand was very sore and a red patch around puncture seems to be getting larger? was wondering if maybe i should go to doctors incase of infection or poisoning due to the copper? its not really swollen much but very tender and red! any advice would be appreciated
