Mine started and is in my feet and ankles making them so tight walking is assisted/difficult and I no longer drive. It started with tingling in the feet progressing to where it is now. My lower legs tingle and have the sensation of being cold but if I touch the skin it is not cold. My surgery was for a part of my intestines that was trapped in scar tissue and being strangled. I found it interesting you mentioned IBS. I had that for about 20 years. After the surgery it is gone even though the surgery was not related to it. It makes me wonder if IBS primed my body for this waiting for the opportunity to activate. Since small fiber neuropathy can affect the smooth muscles I find some functions different from before. No pain. I'm taking supplements, exercising and trying whatever I can that might help me get back to walking and driving. All info and suggestions are welcome as I continue to educate myself on this and will hopefully find the cause to treat it. I'm taking Pregabalin for the symptoms but that is only partially helping. I'm dealing with the rest as I don't want to take a higher dosage or more Rx. I'm taking chocolate and potato chips to treat the soul. 🙂 I'm not diabetic or overweight. Just aging and that might be the cause! In any case, it stinks. 6 weeks before this started I was walking all over a cruise ship and Alaska. That was 2 1/2 years ago. I fear there is no short answer for any of us.
