We all know that using pain killer medicine can be an effective way to treat your chronic pain. Studies have shown that using pain killers such as Oxycodone and/or Vicodin can lead to a longer duration in bed due to the fact that the brain does not recognize the pain signal coming from the body and thus does not send the signal to the spinal cord for it to respond, which is what keeps you in bed. This is known as "drowsiness." However, pain medicines are important when you are suffering from chronic pain like arthritis.
