Dear Sir/Madam, I thank you for having faith in Health Care magic and for seeking help on your issue; I have gone through your symptoms, and in my opinion, you should be concerned with your symptoms as coming of blood is a serious matter, I would recomend you to consult a General Surgeon and get your anal tract examined for any piles of fissure, the hurting of tail bone usually do not cause bleeding, we also need to be concerned for any rectal growth including carcinoma. I hope I have been able to provide you with a satisfactory solution, if you want to clear any doubts about my opinion, feel free to contact. Special note- Any medication prescribed needs to be taken after consultation with your personal doctor only. Thanks Dr. Narender Saini
