Hey Chelsea,
It truly depends on your diagnosis. I would want to KNOW exactly what's causing the intense knee pain for the last few months. I'm no doctor, so take what I say with a grain of salt JMO. Sometimes when a "specialist" isn't willing to investigate a medical problem, they blame "nerve pain" and prescribe Neurontin, etc. I've been on and off the forum for a couple of weeks, so forgive me if I'm asking a question you've already answered. Which orthopedic diagnosed PN? I'd want a second, third...possibly fourth opinion. I personally think you injured that knee. Again, JMO.
My nephew tore his meniscus last Friday in martial arts class. He had surgery on Monday and is in PT.
As for gabapentin (Neurontin) YES, I took it in 2005-06 when I first attempted pain management. The doctor rapidly titrated to a LARGE DOSE with which I could not function. I told him @ 300 mg 3xday, I was okay. He insisted upon the titration to 2400 per day. NO WAY could I function with my career, which is fast-paced, cut throat, and dog eat dog. I was a Zombie. I weaned myself off completely, because I simply could not tolerate the sum total of ALL meds being thrown at me. He didn't care for my participation or input towards my own healthcare. I have never been one to "take this and you'll feel better". If a med doesn't produce results within the allotted trial period, then it's NOT for me. He was the head of the largest Pain Center in the Southeast, but I am the one who lives in my body. When my health insurance went belly up with the economy in 08-09, he was no longer interested in my well-being. The experience left a bad taste in my mouth, so I left PM "forever" to muddle through on my own. I digress.
Mine is a long and complicated story that I won't gift you with on this Christmas Day. I started PM with a local hospital directed Pain Center in January of this year. By June, I was hit with SHINGLES in my eye. I had NO CHOICE but to begin taking Neurontin (gabapentin) again for the nerve involvement. The onset of virus demanded massive steroids and anti-virals to save my cornea. Thankfully, my cornea has not been invaded. However, my eyesight has weakened and blurred. The Neurontin definitely "soothes" the nerve pain in the Trigeminal Nerve center. I remain @ 400 mg 3xday. Some say that is not a therapeutic dose. For me, personally...that's as high as I will go due to the brain fog at higher dosage. The Shingles virus antibodies are still raging in my blood work. I would literally claw my eyeball out (including eyebrow and surrounding forehead, right temple) if not for this nerve med. I don't like it, for many SEs, but I have no choice. Others find great success with Lyrica. I gained weight, which I couldn't accept...so I stopped and the weight came off. If this virus leaves me with TN, I may be forced to endure many side effects vs. suffering nerve pain beyond words. So...It's a personal decision, often finding yourself between a rock and a ROCK. I've learned to use a jackhammer=) The Shingles are the cherry on top of a shart sundae for me.
IF indeed, your problem is nerve related, it's worth a try. If not definitively PN, I wouldn't touch it. JMO...not a medical doctor, nor intended as medical advice.
PLEASE FOLKS...Get your Shingles vaccine! Run, don't walk, to get it!
