Hi Sal, welcome and sorry to hear that you're having problems. Pat (the owner of the site) has put a list of doctors who have a lot of experience and also do revisions on resurfaced hips that have failed. There is also a smaller group of really experienced doctors who will look at your XRays and give you their opinion on how to proceed for free.
They, more than anyone probably could give you an idea of whether there is an alternative to a THR. I would get other opinions, again hopefully from a highly skilled resurfacing surgeon to at least know what the options are.
The way I've heard it, THR technology has improved greatly and with large head MOM, smaller footprint devices like the mini hip and others, are better than they were in 2003.
Here is the page on the site that lists heavily experienced surgeons who are committed to HRs, who I believe also do revisions and THRs - you can look for someone in your area. Also Drs. Bose, DeSmet, Gross, (don't know who else) will look at your XRays and other information for free and give you an opinion.
