Hi Queen,
I'm so sorry to hear you are still in so much pain! I'm definitely not an expert but something doesn't sound right here. You should be long past the soreness of LIS in my opinion. Especially persistent pain.
I also wonder if you aren't having spasms. If you are then it's imperative to stop the spasms in order for the fissure to heal. I know Valium has some side effects but that really doesn't mean you will experience them... I think just about all prescription meds do.
I didn't have any problem taking the valium. Neuropathicguy took them for a very long time before having his LIS. Fissy also took it to settle her spasms after her 2nd LIS, and there have been a few more boardies recently who did also. It's really not all that uncommon for some to get the post-op spasm-ing...
I think a good stool softener is definitely a must. NG and I both took Miralax and had no problems with constipation. I know we're all different and I'm not trying to sound pushy but if you are still having spasms at 8 weeks, something has to be done to settle them! I think there's other muscle relaxers besides valium that may help...
A couple of boardies took the baths and were able to get the spasms to settle but I believe it took a couple of months.
I hope you are able to get some answers at your post-op appointment. I know this has to be so frustrating and you must be worn out.
I doubt you are in a percentage that LIS doesn't work for. Please don't get discouraged. There have been folks in here who needed more than one LIS to heal since their cuts weren't sufficient the first time. It's still very early for you right now and I doubt that's the case.
