Extra puffy crease on eyelid- HELP!

I woke up one morning a few months ago with an extra crease on my eyelid. It is just on one eye .The doctors have prescribed various creams etc but to no avail and if anything it seems to be getting worse. It never diminishes.It appears to be a problem with the skin above the eyelid. It is like an extra fold and crease and v unsightly. It isn't painful just very unsightly and I can now feel it on my eye so it is affecting daily life. THANKS!
