Borax for Neck Pain

I am a senior. I started to get neck pains. I went to a Chiropractor which helped in a temporary way. I decided to try the Borax water (water last recipe) 1 tsp. twice a day and it helped. I take it 5 days a week and 2 days off. I also have to take my 4000 mg. of Vitamin D that alleviates my lower back traveling pains. I was deficient in my Vitamin D, and had my Vitamin D checked and it went up to 47 ng.
