MY FRIEND HAD A METAL IMPLANT PUT INTO HER HAND.

MY FRIEND HAD A METAL IMPLANT PUT INTO HER HAND. SINCE SURGERY 2 MONTHS AGO HER HAND HAS ALWAYS FELT WARM/HOT SINCE. NOW SHE IS HAVING FLUCTUATIONS IN HER BODY TEMPERATURE FROM HOT AND THEN TO COLD. SHE ALSO HAS NO APPETITE. COULD THIS BE AN ALLERGIC REACTION TO THE METAL IMPLANT? SHE SAYS SHE DOESN'T FEEL WELL.
