Prednisone does help with the inflammation of skin rashes in Lupus. Unfortunately, for many of us, when we decreased or discontinued our prednisone use, some of our symptoms returned and we had to go back on small doses of prednisone again.
If you've been in the sun, you could be seeing the results of that exposure. I guess that the answer to your questions is "yes", it could be both. I know that was not very helpful. :cry:
Peace and Blessings
