I have Actinic Keratosis on my scalp where my hair is quite fine. I have been given Solaraze to use. After using it for three days I have awful stomach pains, could this be the cream? I have also got two red patches come up near it, could this just be the cream causing my skin to react? I am worried it’s more Actinic Ketatosis. I struggle to put the cream in the correct place as the AK is on the top of my scalp
