My mum is at the age of 83, have the pain on her right leg, ( move around the thigh and shin ) especially at the night time, sometimes she couldn't even lie down to sleep, she have to sit on the bed side till morning. Recently, the doctor prescribed her to take neurontin 300mg per day for five days then increase to 2 capsules per day. Just wanted to know more about neurontin and its side effect. Will it works in my mum's case ? Wonder why the pain will move around ? What happen to my mum's leg ? Hope someone can advise me what I am suppose to do ?
