Thanks for writing in. Restless leg syndrome is a common cause of painful legs. Restless leg syndrome also features worsening of symptoms during the early evening or later at night. The characteristic nighttime worsening of symptoms in persons with restless legs syndrome frequency leads to insomnia.
The cause of restless leg syndrome is unknown in most patients. However, restless leg syndrome has been associated with pregnancy, obesity, smoking, iron deficiency and anemia, nerve disease, polyneuropathy (which can be associated with hypothyroidism, heavy metal toxicity, toxins, and many other conditions), other hormone disease, such as diabetes, and kidney failure.
Some drugs and medications have been associated with restless leg syndrome including caffeine, alcohol, H2-histamine blockers and certain antidepressants. There are many conditions which can mimic restless leg syndrome including muscle diseases, joint conditions, nerve problems, and circulation difficulties.
Lyrica is usually prescribed for peripheral neuropathy, which could be consequence of uncontrolled diabetes.
I would suggest that you discuss the possible options for your condition leading to restless leg syndrome and treat the underlying cause for it.
