Question: Hi , for 7 years ive had medical problems. It started with me taking a medicinal mushroom, Reishi, which boosts the immune system, it caused pain in my sternum, followed by 2nd day cough, night sweats and bone pain, then productive cough 4 days in, then sinusitis and then a feeling of head pressure building up to a thunderclap headache 1 month later (i continued taking the mushroom until i made the connection), but doctors ruled out stroke. Since then ive had daily headaches, severe pain in my stomach, solar plexus especially in the morning when i breathe, balance problems, chronic sinusitis, muscle pains, complete loss of libido, abrupt anxiety, personality changes, mood changes (leveled out mood). The reason i know it was the immune stimulating mushroom is because if i take just a pinch of it now 7 years later i start getting sternum pain and then cough, and then i stop it obviously.

Unfortunately antibiotics and sprays heal my chronic sinusitis but does not help otherwise. However, my recent intake 30 days after of 10 grams of L arginine daily divided into two doses did so, enormously. This is noticeable when I stop arginine as the symptoms reappear quickly.

To clarify, the arginine took away as long as i took it:
-my daily headaches, completely.
- My muscle pains, shoulder pain. Completely
-my sense of imbalance like the room is moving a little, completely.
- numbness and tingling in hands, completely.
-Cognitive dysfunction in the form of difficulties to think clearly (brain fog) as well as mental disorder, completely. nervousness that completely disappears as well.
-my daily stomach pain in the solar plexus also completely disappears 90% (gastro examined without success)
- feel the pulse in the head and the neck disappear, basically.
The only thing that won't go away is the twitching in the cheek and calf, but they came much later and MND has been ruled out. All symptoms that disappear from l arginine appeared at the same time as the onset of illness 7 years ago and then I conclude that this has to do with my blood circulation and may be vasculitis when arginine does form nitric oxide. Beetroot juice helps, but not in the same powerful way. Vasculitis is possible. But systemic not likely because my inflammation markers are good.
This is a mystery, and you might ask, why not continue to take L Arginine, for two reasons. 1. Because im convinced i have a inflammatory disorder, possibly autoimmune or infectious. 2. Because i get a sore throat every morning when i take L Arginine. The only side effect.
Gastro issues have been ruled out. Neurologist, MRI. ENT doctors have treated me and thoroughly diagnosed. Ive been checked for lyme, tick borne illnesses. I did have a positive for bartonella. However antibiotics are not helping. I havent been to a rheumatologist though. What might i be suffering from?
