hi i have a dime size looks like a mole Brown with hair like lines across it feels tingly when i rub it and it is humped up more than the thickness of a dime , it started out when i got a small piece of metal shaving in it with stamping oil on it from the factory i work in , gotten bigger over a period 12 years and now there is another one the size of a pencil eraser thats turning brown to about 1/4 from it and one below my ear on the left side of my face , also found 4 small brown spots on top of both shoulders 2 on left side of my chest ,they all feel the same way if i rub them (tingly and just wont to rub them more ) should i be worried ? MRI shows large mass over thyroid and a cyst on left kidney could this be affecting my organs ? sorry i have been off work from a neck injury c3,c4,c5,c6 and have not worked or have the money to pay you ant help would be very much appreciated .
