Pain
"I have Fibromyalgia and severe neuropathy in both feet with burning pain all the way up to my knees.  My local pain clinic prescribed Nucynta (for short term pain) and it completely took my pain away.  I did get EXTREMELY light headed and a feeling like I was high. Since it isn&#039;t safe for your liver for long term use, they switched me to Nucynta ER 100 mg to start.  It took 2 weeks to fully kick in and after a month, I formed a tolerance to it.  I&#039;ve been on 200 mg&#039;s for about 5 weeks now and I&#039;ve already built a tolerance to it as well.  This prescription has been a God send, but, I can only go up to 250mg twice per day.  What will happen to me if I build a tolerance to that?  I&#039;m very concerned."
