While your blood is still high if it's averaging at 140, I would think it's rather manageable with diet and exercise but I don't know if the symptoms you're having is peripheral neuropathy. I don't have this so I can't tell you my experience but I do know neuropathy affects different body parts both inside and out.
Here is a link to the Mayo Clinic about
this. Have you seen a neurologist?/www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/diagnosis-treatment/drc-20352067
I'm sorry I can't help more but maybe others can post responses to you.
