The lesion you describe sounds like an episcleritis. This episcleritis is most likely located adjacent to a pinguecula. A pinguecula
is an elevated area on the conjunctiva (the outer layer of the eye) next to the cornea and iris. Pingueculae are most often seen in the area you describe.
Episcleritis is an inflammation that usually has no long term consequences and if left untreated will usually resolve on its own over 7 to 10 days. Anti-inflammatory drops can usually provide some comfort and help recover a bit faster. Exposure to wind, dust and sun can exhacerbate the condition. I recommend wearing sunglasses
full-time, but especially at this time.
Anti-inflammatory drops like Alrex or Lotemax can be obtained with a prescription. Frankly, there are no good over the counter drops to help in this setting. I would advice against drops such as Visine. Visine will take the red out but the red will come back looking for more Visine. Ultimately, the eye can become "addicted" to this drop.
If you are able to obtain a complete eye exam, I would recommend this. There is no substitute for having an expert look at the eye for a correct diagnosis and proper management. Given your history, I do suspect you are suffering from what I have described above. If you will not be seeing an ophthalmologist
until next week, I suggest using artificial tears (over the counter) and placing cool compresses over the eye for comfort.
I hope this is helpful...
