Visiting doctor tomorrow

Had red bleeding when visiting the toilet after a bout of constipation. All symptoms seem to point towards anal fissure as it went away and then after more hard stools came back. Bright red blood, pain when exerting faces.

Was drinking quite heavily and bad diet so now haven’t drunk alcohol in a week and switching my diet up.

The initial pain and burning after going to the toilet has gone away but during actual going to the toilet and the blood is an issue.

Not sure how much medications would help as it’s been going on for a while now?

Any advice greatly appreciated. Thanks.
