Welcome, DianaMarie, we hope you enjoy our forum. I think you will find it to be quite useful.
As to your question regarding Crohn's disease, massage is not contraindicated, however deep pressure is not recommended for the Crohn's client. If abdominal massage is done, it should be done very gently, as the client will have low tolerance for this type of massage. Moderate pressure, to the client's tolerance, is recommended overall, but be sure to review any medications the client may be on. If the client has a long term use of steroids due to the condition, this can predispose the client to advanced osteoporosis. Some with Crohn's may have had long term use of certain antibiotics, which can result in permanent peripheral neuropathy, and the client may not be able to accurately sense the depth of your touch. Be sure to check on any current medications and their precautions. If the client should experience any blood in the stool, have them consult with their doctor to report the condition. Finally, if you the therapist are not feeling well, it is best to reschedule your appointment with your Crohn's client as they are more susceptible to illness.
I hope this helps out.
