I Have Had RA Plus Shrogens (sp) For 14 Yrs.

I have had RA plus Shrogens (sp) for 14 yrs. At present time I am on Plaquiel and doing pretty good. However, my mouth is so dry my tongue sticks to the roof of my mouth at night. For a couple of months I lost my ability to taste. I lost 13 lbs. during that time, but it gradually came back. I have gone to chewing gum as the medication for increased saliva in too expense. I Was on steroids for 4 yrs., but have been off them for about 8 yrs. Shortly after being diagnoised, I noticed my nails were crooked on the end. If I look at the nails pointing them toward my face, four of them are curved (they look wavy). I read an article about nails, the headline showed a picture of the curved nails (which looked exactly like mine) but did not mention the curve in the article, only the dark strips on the nail. I mentioned my nails with my dr. several yrs. ago, but they weren't really concerned about them. Should I pressure them more. The article mentioned many of the unknown signs of cancer, stating that the dark likes ment cancer in the body.
