I think I may be dealing with internal hems too. I know from a colonoscopy 4 years ago that I do have them, but usually I deal with them outside and it's the pain and itching feeling. For the past week it's been a pressure feeling right inside there and I too feel tons of tissue inside. I have anxiety, and tend to freak out over things that are nothing so I'm trying to hold off on seeing my dr until the end of the week and trying to use preparation H cream inside and making sure my stool is soft as it should be. Hoping I can update you with good news that that's all it is.
One of my friend was also suffering from Swollen internal hemorrhoids few years back. Someone suggested to take Ayurvedic treatment for this. He consulted with a dr. and underwent ayurvedic treat for this. It really helped him a lot.
