Many patients do not know how to describe this feeling. Many doctors don't know about it either. But it is a common problem. So, what happens is, let's say you're sitting (maybe at home or in a car). After a few minutes, you just have to get up and walk briskly. You just cannot sit. Or at night, when you are sleeping, suddenly you just have to shake your legs vigorously. You cannot sleep. All these are symptoms of Restless Legs Syndrome.
Remember, you are not alone. this is a common side effect of kidneys not working properly.
Luckily for us, there is a solution. If you are facing these symptoms, you should talk to your nephrologist about Gabapentin. Describe the symptoms and ask if you can use Gabapentin. It is available in doses of 100 mg and 300 mg as Neurontin in the US and Gabantin in India. Definitely do not take it without consulting your nephrologist who will assess the severity of your symptoms and decide the dosage and frequency.
This drug actually saved me from a lot of problems. It rid me of the symptoms in days.
