Off and on (not every day and not all day) for some weeks, I have been getting this redness on my face. It's as if my face is a bit sunburnt (blotchy), and then later it calms. I've been straining my brain to figure out what is going on. I think I may now know. Maybe I have been having a reaction from the OTC medication Nexium (for indigestion). I'm going quit taking it and see if this stops. It does seem that many of the times I noticed this I had taken the Nexium.
