My husband had severe lower left back pain sweating and freezing followed and complained of his tits hurting. he has had cellulitis n past?

Stone or UTI: The severe pain with sweating and freezing (fever, chills, and sweating) is suggestive of kidney infection. Possibility of infectin with a stone is to be considered. He needs urinalysis, urine culture, blood culture, and kidney ultrasounds. Needs urgent medical care.

Many symptoms: What you are describing seems to involve a lot of different things. There is no rule that says you can only have one disease at a time. Low back and "tits" pain are unusual to be related. The past cellulitis is also probably unrelated unless he has it currently. A viral syndrome can cause a lot of things to have symptoms. Is there fevers, nausea, muscle or joint aches? A doctor will untangle this.
