My husband has recently stopped taking klonopin because of the anger/irratable rages he goes into. The doctor perscribed the klonopin for the seizures/tremors and anxiety attacks he was having from the withdrawal from an alcohol addiction of 20yrs, he has also been diagnosed with the beginning stages of liver failure. He is now been experiencing severe upper leg pains/cramping which make his legs go numb. Can you tell me if this is normal?
