I have been on the using Methyl for 6 years after a dreadful crash. Freddd helped me find the way out and I have been doing pretty good. A few ups and down along the way but generally ok. Many things healed but some lingering nerve damage. The last two months I have been chasing my tail and really can't seem to figure it out. It started with canker sores and a sore throat. I upped the frequency of my injections as I had gotten a little lax so thought that it might be low B12. It seemed to work as the canker sores and sore throat went away. But then they came back so I did some research and figured this sounded like epithial issues which pointed to folate deficiency so I upped my folate and that seemed to help a little and I was good for about 2 weeks. I have not changed anything after those adjustments and now my ears ache ring and my esophagus throbs and aches intensely and I feel chest pressure and my tongue has a burning sensation. It is a miserable experience. When I increase either B12 or folate (separately) the pain intensifies quickly in these areas usually within an hour, so which one is causing the problem? Even the addition of a sublingual can set if off. Here is my protocol: SQ Injections Methy B12 once daily (5-8 mg) 1600 mcg Folate daily L-Carnitine Adeno (twice per week) B Complex Vitamin D I keep the ratio of B-12 to folate always at a level where I take more B12 than folate. Is potassium involved? I don't have cramps in my legs, etc. I do feel a small bit of shortness of breath which I have had from time to time in past. I sure could use some help so any and all advice is welcomed.
