### input:
I m a relatively healthy 46 yr old woman and I ve had pressure in my rectum the last few days. At first I thought my tailbone was sore maybe from running and training for an upcoming road race. My bowel movements have only changed the last week in that my stools are bigger and longer and I m not experiencing any other digestive symptoms. I honestly feel pressure in the rectum that is constant and it s a very strange unfamiliar feeling. I ve had a pain in my upper hamstring (believed to be caused by running). It was high up where your thigh meets your buttocks, so at first I was wondering if there was some connection between this which preceded the feeling of pressure in my rectum. Thank you.

### output:

Hi, thank you for providing the brief history of you. A thorough musculoskeletal assessment is advised. As mentioned, that you were practicing for the run and feels like the digestive systems has some issue due to hamstring pull than there is much less possibility for this. Also, for run you need to balance your diet intake and your run output as well. Due to excessive loss of water during the run practice in the form of sweat and other metabolism there may be a chance for the hard stools. For this I will advise to eat the fruits more to balance the fluid intake and output. Now coming to your hamstring, if I have got a pull or a tear we need an assessment of the muscle to be performed. Also, initially you have to stop training first as it will aggregate the muscle fibers to not heal, and later it may trouble more. Besides, undergoing proper physical therapy before training is advised to get the maximum output from the muscle. I deal with sports cases regularly and prevention is better than cure for the longer runs. With physical therapy they respond well and perform better in a later stage of sports.
