I have just seen an advert for an electronic pen which supposedly gives 'effective natural pain relief' within 10 seconds at the point of pain - 'effective on arthritis, rheumatism, osteoporosis, sciatica, migraines, sports injuries,muscle and back pain.' Has anyone tried one of these? It was priced at £24.99 (cheap enough for me to try but obviously dont want to waste money if someone has tried it, and it is no good - although the company is a reputable company and offer a 12 months money back guarantee on their catalogue). I have not included the name of the supplier so I hope that this question is not considered to be an advert which of course it is not. I have RA and Sciatica.
