hello, 4 1/2 yrs ago my husband had cervical spine surgery for spinal stenosis, he has had to have a physic every 3 or 4 days, during that time he has used mom and prune juice. on sunday am he took his physic, has not gone, on monday he took another physic, has not gone and now tonight he has taken a suppository, still has not gone.. how long should he wait before i take him to the hospital????? and if there is anything else he can do short of an enema.... thank you
