HI--My husband has some serious issues with gout. We have been dealing with it for about 6 years. You can not eat meat, chicken, tomatoes, tomato paste, sauce, shellfish and no alcoholic products. He has gotten in his big toe, elbow, knee, and finger joints. He has tried cherry juice, from the health food store, but as someone else stated, it takes awhile to get into your system. The guy at the health food store stated that it is more of a preventive then a cure.
There is a prescription that the doctor can prescribe that needs to be taken everyday to prevent it. As for getting it under control try going to http://www.micronutra.com/uricinex.html
This product is the only thing that my husband can use to knock out the gout in about 2 days. We have also told a friend about this product and it worked wonders for him too. If you prefer to get a prescription ask for prednisone, which is a steriod, but it does cure the gout pretty quickly as well. However, there are a lot of side effects. Best of luck to your relative, hope they feel better soon!
A rheumatoid arthritis doctor is the doctor that you would need to see. Although, our general doctor is the one that prescribed prednisone and then gave us a referral to the rhematoid doctor, however we never went because he began taking the medication from the website above. Again, good luck!
