This lump appeared yesterday morning, when i move it with my finger it appears to be attatched to a thin clear film. However, after a few hours it gradually decreases in size before dissapearing - only to reappear when i woke up again today. I had a similar thing a few weeks ago, in the same place however it was also gone within a few hours and did not reappear until yesterday.
I have attatched a photo below. Any ideas?
p.s. I am a contact lens wearer.
