Lump on anus

I have a lump on the left side on the edge of anus,not internal or external hemrrhoid. if lump is not big or small, and make you fissures anus. you should change your diet, eat lot fiber and 1 gallon water a day to make your poo soft and come out easily. I have a tiny lump and one small fissure, straight line like from left to right on the lump, it make me pruritus and bother. I change my diet, eat a lot fibers and drink 1 gallon water daily. I work out, like put 40 ( or something heavy...whatever you thought of it )red bricks in the shopping cart to pull and push on the field like football player. I work out 2 hour a day. I lay flat on the bed to pull the left leg toward my face ( try hard toward your face until you could not do it for both legs and depend on you... how many time for each legs). It become flat now and no more fissure in my anus, and no tag I hope it gone someday. It is my experience. I hope you will become healthy and strong again.The lump will be backed if my muscles so weak again. I am over 60 years old man. I have a lump for more 8 months. I wish you all things be good to your healthy.
