<s>[INST] I have pressure in my tailbone/coccyx area especially when I have to have a bowel movement, I noticed today that I have bright red blood on the toilet paper after the movement and my small dark red clots. My stomach feels full as if I still need to go to the bathroom should I be concerned. [/INST] Dear Sir/Madam, I thank you for having faith in Chat Doctor 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 recommend 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 </s>
