My sister has had flu like symptoms (fever , body aches, fatigue) along with painful blisters on her fingers/ hands ( they are filled with yellowish pus, not water and they hurt, not itch). She had these symptoms about 6 weeks ago and they started again this past weekend. Dr. last month did blood work and had no diagnosis. She has had skin issues for years with chronic irritation on her hands ( dry, itchy, skin cuts, breaks, bleeds, ). Dermatologist had her use her steroid cream and her hands healed in a couple weeks. She really hasn't felt ' normal' in terms of her energy level since. Then this past weekend it started again. Otherwise healthy, no weight problems but is smoker. Help! Any thoughts or advice /guidance would be appreciated.
