What is this at the side of my eye? (Photo)

Only on the basis of in person consultation one could give you meaningful advise. Most likely benign lesion, possibly cyst which will need surgical removal. Consultation with a board certified plastic or oculoplastic surgeon is recommended. Good luck.

It looks like a sebaceous cyst from your photo. It is hard to tell with just the photo but excisional biopsy (removal of lesion and sending to pathology) would likely be the best route.

The short answer is that it is impossible to tell based on photos alone and this is going to take an in-person exam and evaluation. I would start with your regular doctor. He or she can evaluate you and refer you to a specialist if they are not comfortable treating it.
Good luck!

Thank you for your question. It is difficult to determine what the lesion is based on pictures. It may be a cyst. I recommend consultation with a board-certified facial plastic surgeon to discuss options for removal. Best of luck!
