Feeling itchy all over is a terrible feeling and I encourage you to seek medical care as soon as possible. There are many possible causes of generalized itching (medical term is pruritis) and only your primary care doctor
will be able to give you an appropriate diagnosis and effective treatment after taking a full history and examination. The possible causes of your symptoms depend on if you also have a rash present on your skin. This could be hives, an allergic reaction, scabies, or a multitude of other dermatological skin conditions. If your doctor is not sure what is causing the rash, he or she may take a small biopsy
. If you do not have a rash present then you need to be checked for various medical conditions such as kidney disease. Dry skin can also be intensely itchy. Either way, it is very important that you not scratch your skin as this can lead to infections. Try to keep your nails very short so that you are not able to open your skin if you do scratch, such as in your sleep. Again, please make an appointment with a primary care doctor or dermatologist immediately to determine the cause of your itchiness and receive effective treatment.
