Neuritis is a lesion of the trunk of the peripheral nerve, in which sensitivity is partially or completely lost, and pain appears. In some cases, there is even paralysis. The cause of neuritis is an inflammatory process. When the tumor grows, it touches the peripheral nerves. In most patients, acquaintance with the disease begins as a result of inflammation of the occipital, trigeminal or facial nerves. Neuritis can be contracted not only in cold winter weather, but also on a hot summer day. Neuralgia should not be confused with neuritis. Neuritis occurs due to infections, bacteria, and viruses. As for neuralgia, it means pain in the nervous system. Neuralgia and neuritis can occur simultaneously in one person, but the nature of the occurrence of these diseases will be different.
