Hello my son has had ulcerative colitis for 25 years and suddenly hes having terrible pain in his ankles, he cant walk, they are swollen, red and sensitive ro the touch. Doctors do not know why but think its connected to the UC. Has anyone had this experience and what did you do to make the pain and swellen go away. Thank you and I hope you are feeling well today.
