I have suffered from chronic constipation for many years and around 6 months ago I had to go to the ER because I had a blockage the ER was able to help me by doing an enema that Brock up the blockage my question is I have another blockage and have tried doing an enema but it didn't break up the blockage so should I keep doing enemas until it does or should I go to the hospital

It is difficult to give yourself an enema properly; you cant afford to have another blockage, so I would say go to the ER. You may want to take a look at your diet to correct this situation; follow advice they give you, or visit your doctor for a consultation.
