I burned my hand with 3 chemicals while cleaning. Approx 2-3 days later redness and swelling to my palm in the area below the thumb about the size of a small lime. Soaked in epsom salt. was advised by mother to try vinegar. Put ice to relieve. Obviously should have researched b4 trying anything. I have a picture of it today. The 1st day just swelling and burning pain that subsided a bit with ibuprofen. 2nd day small blister type thing about the size of a pencil eraser. 3rd day (today) blister the size of a quarter. Still keeping the swelling and pain at bay a bit with ibuprofen. Wish I could add pic
