Medical Cannabis for Treating Pain Related to Fibromyalgia

The goal of this interventional study is to learn about the effect of Medicinal Cannabis (Bedrocan®) on Fibromyalgia patients with pain resistant to conventional therapy. The main question the trial aims to answer are: * Is Bedrocan® effective for treating fibromyalgia-related pain in patients resistant to conventional therapy? * Can a low dosage of medical cannabis taken as a decoction reduce fibromyalgic pain? All patients were trained on how to make the decoction: therapy was started with 100 mg/day (1 folder) and increased to 200 mg/day (2 folders) in non-responders.
