Yes this is normal . Continue to use the cream as directed.
Treatment frequently results in a mild to severe stinging or burning sensation, depending on the sensitivity of the skin, the severity of the sun damage and how long it has been used for. After five to ten days of treatment, the sun-damaged parts of treated skin become red and irritated. As treatment is continued, sores and crusts may appear. These raw areas result from the destruction of defective skin cells. They are a necessary part of treatment. They can be covered with a dressing if you prefer.
Treatment is usually between 2 to 8 weeks long and the skin may look unsightly for a few weeks after treatment completed.
If by raw you mean it is like open skin then perhaps you shouldn't use it.
"Do not use fluorouracil topical on skin that is irritated, peeling, or infected or on open wounds. Wait until these conditions have fully healed before using fluorouracil topical".
It would be better if you confirmed it with your prescriber, just to be sure what his/her intention is.
