Shingles often occurs in older adults, with a high incidence in the spring and fall. Older people should be aware that if you have the following symptoms, be careful if you have shingles and see a doctor in time. 1, the rash is often preceded by a cold, fever, fatigue, alcohol consumption and other processes of low body resistance. 2, the local skin appears clustered blisters, along one side of the peripheral nerve as a cluster of band distribution, the rash is distributed unilaterally in a band. The rash is unilaterally distributed in bands. It mostly occurs in the skin domains innervated by the intercostal nerve and trigeminal nerve. 3, accompanied by obvious neuralgia, severe and unbearable. After regular treatment, the herpes will subside quickly. However, if you have the following symptoms, you are suffering from post-herpetic neuralgia, also called post-herpetic sequelae, and you need to see a pain doctor in time. 1. The pain persists for more than 1 month after the clinical cure of herpes zoster. 2. There are obvious abnormalities of sensation, pain and touch distributed according to the innervation area, and there may be local pigmentation changes. 3. The nature of the pain is spontaneous, knife-like, lightning-like episodic pain or persistent burning pain or tight bundle-like pain. 4. There are obvious sequelae of nerve injury in the affected area, such as itchiness, tightness, ankylosis, twitching or other discomfort. 5. Patients have a heavy psychological burden, depression, or even loss of confidence in life and suicidal tendencies. Then unfortunately suffer from herpes sequelae also do not lose confidence, pain doctors can help you to relieve the pain. Here’s how pain doctors treat the sequelae of herpes 1, antiviral treatment: early antiviral treatment is very important, antiviral drugs such as acyclic guanosine, asiaticoside and asiatic adenosine. This mechanism shows that acyclic guanosine has high efficiency and few side effects in treating herpes, so it is the drug of choice for herpes disease. 2, pain relief treatment: commonly used such as aspirin, go to pain tablets, etc., but the best pain relief effect should be the anti-epileptic drugs such as carbamazepine, gabapentin, etc. Prednisone can eliminate the inflammation of nerve roots when taken early, and can be taken in moderation in the early stage. In addition, vitamin B1, vitamin B6 or methylcobalamin, Enzymes and other drugs can also be used. 3.Interventional treatment of postherpetic neuralgia: the most effective method to relieve pain (1) nerve block: according to the progress of treatment at home and abroad, regional nerve or lesion spinal cord stage nerve block is the most effective method to relieve the severe pain of postherpetic neuralgia, especially for the duration of the disease is less than 6 months, the effect is most satisfactory. Regional nerve blocks include local infiltration injection, nerve trunk block, paravertebral nerve root and sympathetic ganglion administration, etc., which should be applied according to the innervation of the pain site. However, it is important to achieve clear diagnosis, accurate positioning and technical operation to ensure the effect. (2) Nerve destruction therapy: If the above methods cannot stop the pain, nerve destruction therapy can be used: including anhydrous alcohol, phenol glycerol and radiofrequency destruction of the afferent nerves and sensory ganglia in the body, and the treatment should be carried out by a specialist under the guidance of imaging. (3) Spinal cord nerve stimulation: This therapy can be considered for patients with intractable pain who have failed to be treated by the above methods. By inhibiting or blocking the sensation of pain through weak electrical stimulation to the spinal cord, most patients can obtain long-term definite and effective pain relief.
