Can ptsd cause peripheral neuropathy, fibromyalgia down thr rd in life?

Not likely. These issues you mention have nothing to do with ptsd as far as i know.
PTSD. I agree w dr. Harper. Although peripheral neuropathy and fibromyalgia can co-occur with ptsd, i don't know of a causal link. However, significant ptsd symptoms can exacerbate fibromyalgia.
Ptsd. No correlation, but they can coexist in the same individual..
