Arthritis and inflammation of the colon -

Just to be clear about what you are asking - you have what you believe to be arthritis in one/both? ankle(s)? As this by diagnosed and by what type of doctor?

How long have you been taking pain killers?

Are the stomach/colon issues solely related to taking pain killers (i.e. otherwise you are fine digestively) or are these longer standing issues that are only complicated by the medications? What have you tried to deal with the digestive issues properly?

What are the digestive issues specifically (loose stools, constipation, both?, pain, bloating, reflux.....)?
