Whats wrong with my mom's hands and feet?? Not sure if its an allergic reaction or not!!!?

Right when she used this soap to wash her hands at this place, it started happening. Then, as she was using this cheap hand sanitizer from wallgreens, it got way worse. Its getting worse. Her hands and feet (bottom and top) sometimes get really red and there are bumps on them. Were pretty sure its not shingles bcuz if you have that then the bumps are super painful. Hers just burn, tingle and itch. She went to quick care and all they did was give her steroid cream. Help please?? It itches and burns so bad it wakes her up like 5 times every night. Help???
