I was diagnosed with LYme, Rocky Mountain Spotted Fever, Cat Scratch Fever, West Nile Virus, Strongyloides and Toxocara about a year ago, all have been extensively treated as best we can. For one year prior I had dizziness upon standing and my vision would go out for a few seconds as well. The doctors looked at me like I was crazy when I said this. So fast forward to 6 months ago and I took some sudafed and my heart and bp went bananas, and i was in the hospital for 4 days, and ever since, along with the orthostatic hypotension has been intense intense tachycardia when i stand up and sometimes in the middle of the night when I roll over. I just had bloodwork done and electrolytes and white and red blood cell count are normal. My urine showed low sodium - 32, normal range 40-220 and chloride - 60, normal range 120-200. I haven't exercised in a year due to illness and then the POTS, but my height is 6 ft and bodyweight 150. I have tinnitus, whooshing and constant high-pitch ringing, visual snow, pulsing dark spots, floaters, headaches, chest pain, pain in the throat/chest area when I take a deep breath, surging blood flow in my jaw/throat/chest when I get cold or move around too fast, as well as fatigue in my muscles and weakness. Any thoughts and suggestions would help. Has anyone used herbs to help with their nervous system? How much does increasing sodium content tend to help people? Any tests I should ask the docs about? Thanks
