A throbbing pain on the left side of the head is most commonly associated with neuralgia, and treatment should be directed at the cause on the one hand, and medication should be taken to relieve the headache in response to the symptoms of pain on the other. The causes of neuralgia can be seen in various inflammatory and infectious factors, as well as cervical spondylosis and other causes. If you have cervical spondylosis, you can take some oral medications to activate blood circulation and remove blood stasis, such as cervical rejuvenation granules. For symptomatic pain relief, non-steroidal anti-inflammatory drugs can be taken, such as ibuprofen extended-release capsules, naproxen, nimesulide, and brain-clearing tablets. Most patients can get better relief of headache after allopathic and symptomatic treatment.
