Horizontal white lines in nails since starting Remicade

Ever since starting Remicade I have noticed that my nails are starting to get white horizontal lines. I looked it up and it's called Muehrcke lines and I have read that it can be caused by a variety of things but I find it coincidental that they only started occurring since starting Remicade. I have deep horizontal lines on a couple of my finger nails due to psoriasis but I've never had the white lines before. Does anyone else on Remi get these lines?

Thanks for the reply Judy. I have an appt with the doc in 2 weeks so I will ask her about it than. I am actually seeing the doc about some bumps on my chest - I'm sort of fearing them to be skin cancer. Actually I would be surprised if they AREN'T skin cancer seeing since I have been burnt so many times on my chest before - one so severely, the skin blistered, scabbed over, I ran a fever and felt nauseous many years ago :(

Just the normal WBC, RBC, CBC and liver. And no, they are at different growths.
