Praise, this site is going to be a big help to me as well. I have lots of interacting med problems and no one doctor ever wants to spend time doing the analysis so I end up figuring out as much as I can for myself, then running it by the various doctors. Hang in there.If you are already on medication, you can go to your drugstore and ask for the full package insert for each medication. This is the same information that's in the Physicians Desk Reference or PDR. I've found it very helpful in identifying the source of some of my problems.
Also, you probably also know that there are lots of medical support and discussion and newsgroups on-line. If you have some clues as to what your problem is, you can look for keywords via your search engine. Sometimes people put up summaries of all they have learned in their own research into the condition. Also, they give links to more info. Alas this takes time and of course it takes a working computer.
Best of luck with this.
