### input:
Hello,Approximately 1 1/2 months ago, I went out of work due to lower back pain. I am receiving ongoing treatment for this. I was prescribed Percocet for the pain. I began taking them daily, approximately 10 to 25 mgs per day. I also noticed that this caused frequent constipation. I used Milk of Magnesia and laxative pills multiple times a week for this. (I know that continuous use of these things is not recommended, but I figured I would probably only be using them short term.) I stopped taking the Percocet 6 days ago; however, the constipation remained. For the first three days after I stopped taking the pain medication, I ate very little, drank massive amounts of water, and took Colace stool softeners. I could only pass liquid, and I could feel there was a mass that I can only assume is fecal matter in my lower abdomen or possibly colon. Then I tried prune juice, organic bowel cleansing powder, and still only liquid would pass; I could tell that the mass was not moving very much. Yesterday, I tried taking Milk of Magnesia again, then later magnesium citrate, and a saline laxative enema, and this morning, I took about 50 mls of mineral oil. Only liquid will pass.I do have an uncomfortable bloating feeling; however, I do not have abdominal pain, nausea or vomiting. I can feel liquid moving through my abdomen when I take it in, but this mass remains. I have now exhausted every option I could think of. What would you recommend at this point?

### output:

Here your main concern is back pain, for this I suggest to check do you have radiating pain from your back to legs or numbness or tingling sensation from your back to legs. If yes then it could be related to nerve compression at your back along with lumbar disc problem. However the conformation can be done only with MRI scan. But if you have only pain at your back, and it does not radiate to buttocks or legs then it will be only muscular back pain. For both of this issue you have to visit orthopedic doctor. Suppose if there is major problem in MRI scan report then or tho surgeon may ask for surgical correction. And followed with physiotherapy treatment to relax the soft tissues and for suggestion on spinal exercise. But if there is no major problem in MRI scan then doctor will suggest for medication for relaxing the soft tissues as well some vitamin B, calcium and vitamin d tablets based on requirement and further treatment again with physiotherapy management. Now the next concern is on your abdominal discomfort and bloating of abdomen. Here for diagnosis two test has to be done. One is ultrasound abdomen and second is colonoscopy to check the problems with abdomen and colon. After this as per the report treatment has to be taken. I suggest Don't take any blind treatment on your own and consult specialist since you are suffering from all ready from more than 10 days. Take care.
