A high B12 in the face of an almost out of range MCV (high)is a problem. You should have a lower MCV with that B12 result.
1) either you took vitamins with B12 in them when the test was run --and hence this would give a false elevation--so your result is rather meaningless....

2) or you cannot convert cyano form to methyl and the test is reading cyano floating around unconverted. This implies a MTHFR mutation in methylation and if so you cannot benefit from cyano B12 form because of this genetic flaw.

Your platelets are low normal. Hard to say if they are on the way down or up with just one test.

I'd take some fish oil or Krill oil to help lower those triglycerides.
About 3 a day of fish oil, or two Krill regular strength or one super Krill daily with food.

I'd look at your diet...eliminate sugars and junk carbs as much as you can. These irritate nerves and cause alot of grief. They lead to impaired glucose metabolism which leads to slow progressive nerve damage.

I would stop drinking alcohol if you do so now.

If you have the MTHFR mutation you will need methylfolate too, as both use the enzymes to add and activate both vitamins so they can work in the body for you. This genetic mutation is pretty common we know now, but most doctors do not test for it yet sadly.

Consider going gluten free for a while. Some nerve symptoms will occur with gluten intolerance. And also get some magnesium lotion (Morton Epsom Lotion) for muscle twitching and cramping. The nerves use magnesium to block pain signals from the NMDA receptors too, and also mag helps improve circulation to the feet and hands.

Are you on a statin, and is that why your cholesterol is low?
These drugs cause lots of nerve and muscle symptoms.
Do you take blood pressure medication? If so what type?
