The fibromialgia is a chronic upheaval that affects mainly to women among 30 and 60 years. The clinical picture includes psychic pain, fatigue and upheavals (especially upheavals of the dream). Other symptoms can be paroxsticos movements, cramps, migraas or muscular spasms. The pain usually is so intense that with treatment it even can not disappear. The fibromialgia is very difficult to try and for that reason usually it resorts to a multidisciplinary treatment that includes rheumatologists, physiotherapists, psychotherapists or attending physicians. The pharmacological treatment includes nonesteroideos and antidepressing antinflamatorios, although their annoying indirect effect are known as much short very well as in the long term. As far as the nonpharmacological treatment, options like the exercise (particularly the aquatic one), the occupational therapy, the nourishing supplements or the marijuana exist. In spite of having contraindications, the marijuana acts like a powerful muscular relajante and calm the pain, reason why it can be very beneficial for the fibromialgia patients. To buy marijuana seeds, as well as to sell them, are completely legal, reason why it turns out very simple to take control of them.
