Small Fiber Neuropathy?

Posted by elsa @elsa, Jan 23, 2019

Hello. I'm a 64 year old woman who has a complex medical history. I have relapsing-remitting MS (diagnosed in 2006, well-controlled; on Copaxone). I also ruptured my L5-S6 disc in 2009, subsequently had a microdiscectomy during which the surgeon tore the dura. Since the surgery, I developed chronic pain which worsened with time. Last March I graduated from Mayo's 3-week pain management program. Since then I no longer take any opiates or benzodiazepines which has been a huge step for the better.
That said, in the past few months my pain has spread and changed in nature. I now have bilateral burning sensations in my buttocks and hamstrings. This new pain seems to be burning in the outer part of my skin. It burns whenever I'm sitting or lying down. Any pressure at all on these areas causes really awful burning sensations. I am wondering if I have developed small fiber neuropathy.
Questions: 1) Does my description of this new pressure-sensitive, burning pain sound like it's SFN? 2) I notice that there is some discussion about immunity and SFN. Could my having MS (an autoimmune disease) somehow be causal in the development of SFN? 3) Can anyone recommend a doctor at Mayo in Rochester who could examine me and do the proper tests to hopefully diagnose what's going on?
Thank you much!!

No concerns about stopping Gabapentin.... want to find something which helps... It seems I am not alone on this quest..

Hi Jake
What has formed your "uneducated opinion" about hypertension and TCA's?
I am not aware of any issues with BP and TCA's, unless the patient is also taking Clonidine (not clonezepam or Klonopin)

I thought I read that somewhere, I think on Harvard News.
My dad started taking it and had blood pressure issues but he was a C-5 quad.

My uneducated opinion is not to expect a decrease in blood pressure as long as your taking a
Tricyclic antidepressant.
Try stopping your Imipramine. Bet ya a nickel your pressure goes down. When did it start to increase?

I know that it coincided with starting Imipramine, but looking at drug interactions between that and the antidepressants I already take, elevated BP is a common side effect. I really hope that I'll be able to keep the Imipramine because it's the first thing that has relieved my pain. Higher BP isn't listed as a side effect of just Imipramine itself.

No complaints? try stopping it. Cutting it by 25% is a lot especially since you have taken it so long. If I was your wife I’d kick you back, good and hard. A little unconventional perhaps but it just might work.
Klonopin isn’t easy to get off of. I took 18mg but had an uneventful taper but it took a long time but I didn’t take it for years.

I don't plan to stop taking Clonazepam any time soon. One of the things I'm going to try is cutting back on the Imipramine from 100mg to 75. I don't know at which level my BP went up.

NEVER stop any Anticonvulsant which is what Gabapentin and Lyrica are if you have a seizure disorder. Could be deadly. Don’t think that is an exaggeration. Before I knew better I quit and lost 15 years of my life, 8 months in a coma and nearly my life. Never stop any medication on your own.

Your warning is a very important one. I've done a ton of research on Gaba and based on what I've seen, no one should ever stop taking it cold turkey - even if they do not have a seizure disorder.

The first medication my Neurologist suggested was Effexor and I IMMEDIATELY declined. I was on it a decade ago to treat depression, and the side effects were horrendous (including those during the weaning process). Many people say the same things about Gaba - so I knew it could be bad before I started to take it.

Truth be told - there do not seem to be a lot of pain management options for nerve pain, and quite frankly I am tired of being in pain so I'm willing to roll the dice on this one. I am watching carefully for side effects and monitoring how well it manages the pain. Eleven days in and so far so good - but my doctor started me off on 100 mg for 7 days; 200 mg for 7 days, then 300 mg for 14 days. I take it only at night and need to go back and see him before the end of the month. I have been sleeping through the night pain free (yipppeee!) and cannot wait to be able to take it during the day.

I combine those two meds with 5mg hydro/325 acetaminophen and 1000 mg intravenous lidocaine infusion.

What is 'hydro'? Every time I see that word here all I can think of is hydro electricity...
