I Took Flouorouracil As Prescribed.....topically On My Face As Prescribed

I took flouorouracil as prescribed.....topically on my face as prescribed in late August. Several weeks after finishing I had strange symptoms......bloody nose,hypersensitive gums,easy bruising,slight scatch causiging minor bleeding and last but not least mouth sores......most all symptoms have gradually minimized except for the last one to arrive .....the mouth sores.

What if anything should I do to speed up the healing.

The prescribing source is saying that they have not heard of these symptoms.......see my GP ?????
