Problem with local anaesthetic for hair transplant :( CAN ANYONE HELP!!!!!!!

[silverclerk]

Hi there, I've gone twice to have a Fue procedure. But on both occasions I have had bad reactions to the local anaesthetic which was Lidocaine the second time. I had a patch test the day before the procedure and was ok.
I was given 4 injections of the local anaesthetic in the back of my head, adding up to 5mg, I was ok for the first 2 then after the 4th one my stomach felt funny, I had an irregular heart beat and my face was as pale as a ghost.
I was wondering if anyone else has had local anaesthetic issues? or knows what options I may have?
Thanks
