Try a high quality chelated Magnesium. If you know a naturopath seek a Practitioner only quality supplement like Ultramuscle ease (Bioceuticals) or Fibroplex (Metagenics) or contact the company direct for as a physio you can order once setting up an account.

90% likely to work and if it does, 100% likely to transform your practice. As a Physiotherapist and Nutritionist I am confident once you learn about Magnesium and other nutrients as addendums to your physio. you will change your practice.

PS Tragically, very little research for magnesium with the exception of tetany and fibromyalgia so I can't please the EBM connosseurs here.
