If anyone can help I would appreciate it. I jumped off a high platform a year and a hlf ago and compressed my L1 vertebre 60%. I immediately suffered from constipation. The docs said it was medication. 10 days later a large dose of Lactulose made me go but I have suffered ever since with chronic constipation. I juse given Zelnorm 4 weeks ago and it worked great for 1 week. Anyone out there that can help with what works for you please share.
