Meghan,I have several meds I take to help with my nerve injury. I do the medication cocktail thing. Currently I take Neurontin, Trileptal, (anti-seizure type meds), Effexor (antidepressant) and Ultracet (pain reliever).
Finding the right mix of medications for you may take some trail and error. I have changed my meds several times in the last five months. I expect changes again at my next visit with my doctor. I visited my doctors every few weeks in the beginning and now I'm out to about every six to eight weeks. I think it is important, especially in the beginning, to visit your doctor regularly to follow-up with how you are doing.
I have noticed a decrease in pain level since beginning the Trileptal. My depression and pain have benefited by adding Effexor. When I was switched from Remeron to Effexor my doctor put me on both and slowly decreased the Remeron while increasing the Effexor. Just do things slowly if you can when you change your medications.
Something else to think about is that chronic pain is notorious for causing depression. A few of the side effects listed for Neurontin also can be signs of depression so make sure that is not what you are struggling with too. It isn't anything to be ashamed of or embarrassed about, but it is something that can be treated. Many of the medications for depression are good for nerve injury pain. Dealing with chronic pain is not easy and finding the right mix of medications to help ease your pain can be very stressful.
Your descriptions reminded me of some of the feeling I felt in the beginning of my pain adventure. Your symptoms may be caused by medication, depression or both? It is important to talk with your doctor and figure this out. I had both and I needed to change my meds around a bit to feel my best.
Good luck.
