Allergy effect on my leg implant.

Hii,most of the time i experience itching sensation on my skin where metals being on contact with my skin for long time like on my stomach because of belt buckle and on my wrist because of watches with metal base.After i use to itch because of irritation it frequently comes with rashes.so i stop using belt's but still wearing watches regularly but no itching on wrist only few times. Now i just gone through a fibulo bone leg surgery 20 days ago because of an accident n placed n titanium plate with 6 titanium bolts does this titanium plate will give any bad effect to my skin or muscle??? No itching till yesterday but after the removal of stitches i got little bit itching i guess because of healing wounds but not sure.
