I have tingling in my arms and legs all the way to my toes. My neck is a little bit swollen and tight. I also have joint pain that comes and goes pretty quickly and moves from one joint to another. My vision is also a little bit blurry. I have had these symptoms for the past 4 or 5 days with yesterday being the worst day and today it feels like Im getting better. I feel about 50% better today than I did at my peak. I was still able to get around and do my job with what I had going on but it was very worrisome and annoying. If you could give me a few guesses of what it could be I would really appreciate it! I was thinking maybe it was caused from my well water because I stopped drinking yesterday and I feel better today. Also my roommate had some of the same symptoms but it didnt sound as intense as mine. .
It could be some intervertebral compression problem in any region including cervical and sacral region where emanating nerves are compressed by arthralgia or arthritis or any disc problem. One manifestation could be RA and sugar levels. Some tests like Blood sugar, ESR, RA test, X-Ray reports of vertebral column/ spine at cervical and sacral region is needed for proper comment. Till then, you may arrange to Chat Doctor.  You will get good response if you take for a week. No side effects. Hope it helps.
