I have severe itchiness and pain on the left side of my upper body, my whole underarm, breast area and back is extremely itchy, its driving me insane! I have these lil red bumps by my breast and what appears to look like hives on my back. I also feel a dull ache. It all started when I changed my deodorant and applied to to my newly shaved underarms, but it's only all on the left side. I have no fever but I have been feeling lethargic, any idea's? Thanks!
