Wanna say: believe what you see, not what is told to you. This applies also to the so called scientific authorities. I have quite a experience with being told different stuff. Not really with magnetic therapy, very little, but a lot with arrogance of people telling me that X should not work, although it is working for me. Or a restriction to methods which could be a help to my sufferings, but because X decision taker does not believe in them, I can’t get the info, or the medical support, and so on.
A case:
I have 16 years now polyarthritis (I am 42) due to an auto-inmune disease, with in total 15 articulations (yep, also fingers and toes and joints which we aren’t to aware) involved. After 6 years of massive standard therapies in Germany (huge menu of pills -now I hate pharma-, rows of analysis, rheum-specialists, OPs, a lot of orthopaedists, and so on) I got to alternative methods. I swear, I wasn’t fond of alternative methods before, I have still an allergy to esoteric discourses, but I was desperate, nothing was working. And because I am the one suffering it, I don’t care too much about what is told me to use, instead, I test out to find what helps. That way I got to acupuncture and homeopathy (which works with me a lot, but for each I only found one really good doctor, the rest don’t seem to know what they are doing). Other alternative therapies did not work, or do for specific parts, and not for others, and so on (aloe on my ankles helps with inflammation, but not for my knees, for my knees a compress of vinegar and salt has the same 72 hours effect than diclofenac 50mg). I just got to the point where I think there are many medical theories, and all have for me the same value and authority: I test them, and if they work, I use them, and don’t care about what they say about others. So, I don’t care what classical medicine (which is quite arrogant for its youth) pretends to tell me about lets say acupuncture. All are only perspectives.
Case Nikken:
This way, 2 day ago, my actual hurting joints, both knees, after some weeks of intense pain, got a unexpected release: I was lying in a bed of a lend apartment, I was testing different pillows to put under my knees because I can’t stretch them due to inflammation (chronic sinovitis) and there was lying around also a nikken pillow. I felt instant release of pain, which meant that in the morning I didn’t need 5 minutes of painful walking to stand without something to lean on (I just could walk directly), and I was still some kind of stiff, but with a lot less of pain = a state about 2 week ago. Surprised, when I saw Nikken on it I thought “ah, again that as useless as expensive wellness merchandising”. I too, before of last night, had not tested it.
Tonight I found in this house a mattress with magnets, Nikken too. I lay on, and after kind of 30 seconds, I could stretch my knees, something I could not make since more than a year. And today I could, for repairing a curtain, climb a chair in 2 seconds, which I did yesterday in 15, for I could bent my knees more, and mainly tense the muscles without pain.
So, for me, it works. Gonna buy them.
If we want a theory (of course I also search explanations), I guess that it releases tension. What I believe: When you have chronic pain, your body is kind of afraid and over tenses continually muscles. This leads to massive pressing on sensible points. I don’t care about the blood flow here (anyway, your argument of red tint of skin as a proof is not too good, you have to move relative much blood and quite close to skin, where the conducts are thinner, to see something. with your first I agree, with the last again not), but I know we have a lot of electricity in our body, all the synapsis stuff, which does not only has to do with brain neurones (I would never place a strong magnet close to my head) but also muscles info. That is what I think has led to my internal relaxation and pain release effect.
Ok, resuming: don’t believe what one side or the other tells you. Nor our contemporary 200 years old medical science criteria, nor Nikken vendors. Nor me, it can perfectly be that it does not work out for you and you throw a lot of money trough the window. Just test it for yourself, and care for your personal relieve.
