Loss of libido
Fibromyalgia can cause cramps in muscles around the pelvis and lower back during sexual intercourse. This can lead to immense pain in these patients overriding the pleasure of intercourse. Studies have reported gradual decrease in sexual activity over time in these patients.
Doctors may advise painkillers such as duloxetine and antidepressants such as paroxetine and sertraline to decrease the pain and increase sexual desire.
