Skin Loosening Condition

Patient: Do you know of a condition that could make the connective tissue in someone’s skin start to feel inflamed, painful, and itchy and then, make the skin loosen? This started in just a few places and then, spread to the whole body. Also, this is NOT loose skin due to weight loss and I’m still quite young.

Symptoms: Itching, loosening, skin is excruciating painful if pressed on
