Unfortunately the stabbing is a part of the disease. It has ups and downs. Sometimes you get them a lot then you will go weeks without them. The only thing good about them is the pain subsides almost instantly. It’s painful ( unimaginable pain) like being stabbed but it’s like when the knife comes out the pain goes away and there is no residual pain after. But I would be so worried when the next one would come I would tense up. That tensing up made my neuropathy worse.
I hope you can find some comfort. It’s a cruddy disease.
