I got the treatment done in Spring 2004 and it's crippling me. I now have arthritis and getting by each day is a struggle. Something in those replacements certainately doesn't agree with me. Im not working at the moment as im simply unable to. So i took the chance to stay with my girlfriend in the US as i feel better here(not as many mobile phone masts around) I start to salivate whenever im near them..crazy but true. Obviously the metal in my mouth is acting as a conductor and there are times when i honestly think i can hear TV in my head when it's not even on and thats when it gets scary. I won't get them done by the NHS as im going to have them done over here in the US. In fact when i do eventually get better i doubt ill ever walk into a NHS surgery again
