Yes! Thirst pains are as real as hunger pains. It often happens that we have pains such as headaches, joint pains, and ulcers that more often than not are due to dehydration. A dry mouth is not always a reliable indicator that your body is asking for more hydration. Amazingly when we are dehydrated, there is not sufficient water to rinse acidic waste from our cells. It is then when the nerves wrongly interpret the shortage of water and acidic in the body as pain.
