1.What is the harm of pain? Long-term pain can make the heart beat faster, increase blood pressure, increase the load on the heart; respiratory acceleration, increased oxygen consumption in the body; even cause endocrine imbalance; gastrointestinal function inhibition, indigestion; inhibit sexual function; let people become anxious, worried, withdrawal, irritable. Severe pain can overwhelm a person and cause him or her to lose the will to live. Therefore, pain is a serious problem and treatment of pain is urgent. 2. Can pain be controlled? With the rapid development of the pain profession, many pains that could not be controlled are now available with many effective measures. With a series of integrated therapies such as nerve block therapy, medical imaging minimally invasive interventional analgesic therapy, drug therapy, semiconductor laser therapy, etc., more and more people are getting away from the torment of pain. 3.What is nerve block therapy? Nerve block therapy is one of the most common treatment methods in pain medicine. The doctor injects drugs into the nerves around the patient’s lesion or lesion-related parts, and the local anesthetic can block the neurotransmission of injurious stimuli, leaving the nerves in a semi-dormant state, thus activating the self-adjustment and repair within the nervous system and its innervated areas, plus the action of some of these neurotrophic drugs to achieve the treatment purpose. The treatment has the characteristics of minimally invasive, less medication, good efficacy and less side effects, so that patients can get the maximum efficacy with the minimum cost. 4.What is medical imaging minimally invasive interventional analgesic therapy? Minimally invasive interventional therapy adopts the joint guidance of imaging and neurologist, under the precise navigation of CT or C-arm X-ray machine, selective and precise lesion treatment, or destructive nerve block, through blocking the transmission of pain signals, eliminating local inflammation or relieving the compression of nerves; so that the intractable pain can be relieved or eliminated, and it is especially useful for various neuralgia, plant nerve disorder, headache, cervical and lumbar disc herniation, trigeminal neuralgia and herpes zoster. Trigeminal neuralgia, post-herpetic pain, cancer pain and neurogenic pain have unique efficacy. It has become an important development direction in the treatment technology of painful diseases. The treatment is effective, less traumatic, quick recovery and less complications, which is especially suitable for painful diseases that are not suitable for surgical treatment and the effect of drug treatment is not ideal. 5.What is the therapeutic effect of semiconductor laser? Semiconductor laser treatment can stimulate the body’s defensive immune function, promote tissue regeneration, strengthen the endocrine system to regulate the body, promote local blood circulation, so that the concentration of local pain substances is reduced, thus producing anti-inflammatory and analgesic effects.
