I was diagnosed with psoriasis quite a few years before it started to affect my fingernails. Now, I won't get into the particulars about how terrible my nails reacted to the disease, but I will tell you about the BENEFITS I have experienced. First, my nails are nicely thick. NOT gross, but thick enough that they don't break easily. Also, they are STRONG. I swear I could use my nails as screwdrivers. And they grow fast--almost unnaturally fast. I could grow my nails as long as I would want them to be, but these days I keep them at a reasonable length. Years ago, I gave Dolly Parton a run for her money in terms of nail length. However, I am much more comfortable with shorter nails these days.
While I will have manicures at times, I find that NO ONE does my nails as well as I do. I really wish I could be happy with how my nails look when someone else does them, but there always seems to be SOMETHING wrong with the way they are done. And because I have to have my nails polished at all times to cover up the psoriasis damage, I spend far too much time doing manicures. Believe me, I wish I could go without polished nails many times. But even being on Enbrel hasn't completely made my nails look normal. :(
