Hi I stumbled across this forum while looking for answers to my symptoms. Bit of background, I'm 44, female and recently lost 60lbs. I'm about 175lbs now. I've been concerned about possible colon cancer for a year now due to various tummy grumbles and a reflexologist who told me my descending colon was congested. I also should say that I suffer from health anxiety. My GP seems to think it's just ibs. The only symptoms I've had are a bit of mucous in stool and upper left abdo pain. Anyway, the reason I'm here is I have a whole new set of symptoms now. I've had lower back pain on and off for years but it's constant at the moment. My SI joint is tender when pressed. I have numbness down the back of my left thigh and numbness in my left little toe. My wrist joints are also very painful. I've had tailbone pain on and off for a couple of weeks although that's gone now. The main thing at the moment is pain in my rectum which comes and goes. It's not as bad when standing, seems to be worse lying and sitting. I've had the fleeting knife like pains in rectum which make you catch your breath a couple of times too. Also sometimes when I get up from sitting I get a sharp pain in my right hip which makes me cry out. The main thing though that's worrying me is the rectal pain and leg numbness. I have a doc appointment on 7 March but until then I'm worried it's something sinister. Can anyone help who has similar symptoms?
