My Husband Thinks He May Have Shingles. He Took A

My husband thinks he may have shingles. He took a shingles shot approximately 2 months ago. Presently his health is good and he has always had a bout with atop dermatitis. What has happen recently are lesions, bumps, patches, red sore spots, whatever that are under both arm pits, his back, sides of his torso and both inner thighs, that have a burning sensation for no reason, and is intensified especially when deodorant is used. I disagree with him because there is no pattern of the lesions and it is affecting both sides and not just one.
