Thanks for good tips.
But I'm worry about the feeling that something stuck in my throat also. It was happened together that blood in the stool and feeling of fullness in the stomach.
Because it's bright red and your experience hard stools, I feel this is your hemorrhoid or you may have a small tear in the anus from the hard stool, both are benign conditions. Nothing develops in the colon within 10 months so I wouldn't worry about that. Make sure you eat enough fiber and drink plenty of water. You want to avoid the hard stools and straining, so if this doesn't help you may want to add a stool softener like Miralax (not habit forming) to help with your BM's. Let us know how you're doing.
If the color is bright red, then that would indicate that your hems are bleeding, especially with a hard BM.
Do you bleed less with a softer BM?
However err on the side of caution and go and see your Dr about this
Hope this helps
