i dont think u shld use fake nails for more than a
week.
it happened to me b4, better go manicure, ask them to remove
those glue on ur nails and have a treatment. 
I didn't know we can't use fake nails for more than a week. My
friend ALWAYS use fake nails leh. Hope her nails are still ok^^
I've removed the glue already. Better go for Manicure soon!
