I had an electrical solenoid explode in my hand in october last year. The burns were 2nd degree. I had it checked over at my GP surgery. It has been healed for some time now, its not hot to touch or red at all. There is a little bit of surface scarring but nothing that visable. However, i have been getting pains in my hand under and around the previous wound. I am a little worried about it as i am affraid of it being damaged internally and something i cannot see
