I'd recommend reading "How not to die with True High-Dose Vitamin D Therapy" by Tiago Henriques. Brazilian Dr. Coimbra uses this to cure MS. My guess is that it might also be effective with other neurological problems. My endocrinologist prescribed 50,000 IU/day for me as being vascular protective. I haven't read the whole book, so this is just a "check it out", not an endorsement.
The protocol involves a low calcium diet and blood tests for D, parathyroid, and calcium. The target apparently is to reach the highest D level that doesn't cause problems with calcium or parathyroid.
It depends ENTIRELY on the type and ACTUAL cause of neuropathy. What antibiotic is this being attributed to? The only ones I coul think of immediately are antituberculars. But no, here are some others---none used any too frequently. Depending on the antibiotic, you might be able to find the putative MECHANISM of its causing the neuropathy somewhere, and go from there.
Has she had a nerve biopsy, or is this speculative?
Louise B Andrew it wasn't speculative, the symptoms were very real, but it didn't get to a biopsy. Good news is they have faded and are now gone. We are attributing it to an allergic reaction to a drug.
I can check the name but it's one related to Fluoroquinolones, which have a number of case studies and articles written on them and neuropathy.
I didn't mean to sound pejorative. What I meant was, was this diagnosis essentially a guess by a provider, or was it proven pathologically? I would always assume (well, almost always) that symptoms are real. At any rate, good that it's gone. It wouldn't have had to be an allergy, a side effect could do the same thing without any allergy per se.
Fluoroquinolones, while occasionally necessary (I had to take them once, was a worrisome week) have MANY awful potential effects. Best avoided unless they are absolutely necessary IMO.
As mentioned above by @katherine, I use photobiomodulation with red light, along with massage:
1. I put together two 500 watt halogen construction lights and a heat sink made of drinking water bottles with red food coloring. I lie in bed with that shining on my toes for 20 minutes at a time.
2. I bought a foot vibrator (ordered from China), that has red LED lights built in. I sit in my rocking chair with one foot at a time on that.
3. I get foot massages (a sub-set of Thai massage) 2-3 times a week.
In addition I take CoQ10, Acyl-L-Carnitine, and Alpha-Lipoic acid.
I avoid doctors so I haven't asked for "permission" to do any of this.
Is it helping? Certainly. Maybe. I take so many other vitamins and supplements, and do some exercise, that I can't be sure what is actually causing the improvement.
