Skin Rash, Serve Itching. Has A Titanium Plate In Neck. Intensity Of Itching Increase After Metallic Taste Starts?
Thanks for posting your query.
As I understand it, your husband has newly detected hypertension, attacks of atrial fibrillation, and severe chronic allergic rash that you relate to the placement of Titanium plate in his neck.
Titanium normally is quite neutral and does not lead to problems; but no one can predict how the individual will react.
As you have already been to so many dermatologist and allergy specialist for your husband's rash concern, I believe, they must have ruled out the major and common causes of rash.
For metallic taste, he can try taking acidity medications like Omeprazole on empty stomach, if not tried before.
However, it feels like all the treatment modalities which he tried till now failed for itching and since 2 and a half years have passed, you can talk to your doctor if he can consider removing the titanium plate after evaluation.
Till then, continue anti-allergy drugs and Prednesolone as suggested by your dermatologist for the itching.
I hope, this answers your query. Please accept my answer in case you have no follow up queries.
Regards.
