I am waiting to see a surgeon about a hip revision. I had a hip resurfacing 21 yrs ago and have started having pain in my hip again. I was tested for Chromium and my levels were flagged as high. An MRI did not show anything wrong with that hip.I also have my other hip and both shoulders replaced all due to arthritis. I am now hypoglycaemic which is a side effect of high Chromium and have other side effects, fatigue and tin taste in my mouth. My biggest worry is do I have to have them all removed and what do they use instead of metal, or could it be just one joint causing the problem. I read that hip resurfacing could be a bigger problem when it comes to a revision. Any input would be appreciated.
