Hi, I have severe health anxiety that has been easing lately but now I am experiencing symptoms. About 3 weeks ago my lower back started to hurt like a dull ache and it would be in my left bum cheek and then sometimes in the back of thigh. At different times of the day I get a shooting pain in my groin on and off on the left side but I put that down to ovulating. Anyway I felt like I kept needing to go the toilet and then when I did go there was a lot of yellow mucus. I started drinking more water and was going the toilet 2 to 3 times a day with what looked like a healthy stool. If I forget to drink water for one day I am constipated again and the pain gets worse in lower back. I'm frightened because I am going to toilet 3 times a day sometimes twice for the last week and I haven't ate a great deal because I have an eating disorder and I just don't feel like eating with the stress. Again went this morning to the toilet after waking up with a dull ache in my lower back and there was mucus but nowhere near as much as the other time. I am so worried it could be something serious and I am going to see my doctor tommorrow but I'm petrified incase they tell them something is wrong. I eat Weetabix for my breakfast every morning and I have either beans on seeded toast or something smallish for my dinner. I rarely eat anything else throughout the day only maybe a chocolate bar every now and then. I don't get exercise either as I am too afraid to go out alone. I'm hoping after explaining everything someone could help me. I have been drinking a lot more water but still have this back pain and feeling like I need to go the toilet. As I say since drinking the water I have been going the toilet 3 times a day but still with back pain. I am so scared
