<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just got a knot on my right temple a few days ago. It s the size of my little finger. It only hurts when it s touched or if I lay on my right side. I ve not hit it and it s not red or doesn t even look like a pimple. I have no other symptoms other than one day, I had what I thought was pink eye. But that went away the next day. What could this be?  <response>: Hi.based from your description, it could be a fibrous fibrous tissue formation, a lipoma a fatty deposit or a cystic formation sebaceous or gelatinous type. Other types of lesions must also be ruled-out. A consult with your doctor is best for clinical evaluation, especially if the lesion is bothersome for you. Diagnostics and management will be directed accordingly. Hope this helps. Good day!! Chat Doctor.
