Two nights ago while doing laundry (including picking up old clothes in the bottom of my closet floor to wash) I noticed a red area on the crease of my elbow that was almost a perfect square, 1.25 inches or so. Assuming it was a bug bite as bugs are common in my building, I ve tried Benadryl (no help), as well as hydrocortisone cream and caladryl. The creams help, but when I come back up my apartment the redness goes back to what it was at first. It doesn t itch but is warm to the touch. Only other detail worth mentioning is a few hours before I got furniture/wood stain on my arms and legs and used a wipe to try to get it off - maybe it reacted just on my elbow? I don t know. Help!!!
