If Valium helps it means that you are still having some spasms and tightness going on : (((. Especially if you have trouble passing soft poop . Maybe you can ask for manomerty test (to measure your inside resting pressure ). Did you have recent CRS exam - sometimes they can feel by regular exam if you are still too tight. I needed 2 LIS surgeries to make it relaxed enough to heal without set-backs . I am especcialy concerned since you said that there is no way in this world you would be able to push suppository up during those episodes. My sphincter was exactely like that - even when I would succed with great pain and struggle to push it in (sometimes suppository would literray almost brake ) it would be ejacted out as soon as I would let go if it !!!!!!!!!!!!!!!!!!! My sphincter was so tight , I had trouble passing gas :( .
I really hope that you will find lastin sollution soon . Now that 6 months passed your sphincter is back to its final strenghth level. I know exactely how you feel . I ripped my fissure open after 5 months of no problems after first LIS and than had to have another ...
