The Daily Mail covers a lot of health related information, a fair bit of which is covered quite well, with the occasional mis-reported ‘howler’.
This article, possibly, is a good story.
It’s been known for a while that ‘stabilising’ the membranes of the cells in the affected area is important to reduce the inflammatory cascade that is one of the hallmarks of this condition. Indeed, regular consumption of fish oils is thought to have one of its beneficial effects in this way.
This new cream, from Germany, may work the same way - but a bit faster than the fish oil approach as it is topical (i.e. locally applied to the sore area).
Worth a try?
