84? Wow! You go!
Welcome to the forum and sure hate to see your having such a time with sciatica as it is one of the most frustrating pains to deal with as it seems there is only breif relief from any one thing.
As for your miraculous "cure" if only temporary I would say it was more from teh positioning of your spine then the magnetic forces at work.
When it we have a flare up it is generall caused by the nerve having pressure applied to it for whatever reason and by something out of line in the spinal alignement. Most of us will not or can not stand to change to a position to ease up and let off the pressure for the amount of time required to render the nerve back to noncompressed state,the pain is too unbearable but you did since you were trying to complete the MRI and it worked for awhile. When you went home and again slumped back over in the easy chair to sleep it again most likley slipped back under the part applying pressure to begin with.
For example I have noticed when mineis acting up and I am lying in bed if I stiffen the leg effected to the point of tightening all the muscles in that leg for as long as I can hold as tight as I can hold then when I let go I feel total relief for a bit.
I have no experience to the accupuncture though but I know others here have them and will most likely stop in to say Hi and share their experiences and opinions with you.
Hi there Casarena and Welcome to HealingWell!
I cannot claim to be any kind of expert with Sciatica or Magnetic Therapy but I felt compelled to come over and say hi and I hope you get the answers you are looking for here. I dont come across many older people here on HealingWell... Depression is dominated more by 16-25's. I think its fantastic to see that HealingWell is reaching all types and ages of people.
Good Luck to you!
