There are a number of doable explanations on why muscle spasm produces pain. Lewis and his associates31 have postulated that, throughout sustained muscular contraction, the formation of a metabolite that they decision P could be the stimulus for the pain. Still other investigators have produced experimental evidence to point that, in ischemic muscles, noxious agents could accumulate and produce pain. It’s been frequently prompt that ischemia because of occlusion of the circulation could be the factor that produces the pain in muscle spasm. Let Aloe Deep Moisturizing help maintain and deliver moisturedeep inside the outer layers of your skin to revive andpreserve your skin’s youthful glow, and quench your skin’sthirst for moisture like never before! But, it should be noted that the circulation to an extremity will be occluded while not producing pain as long because the limb is not exercised. Elliott11 and Tunis and Wolff30 demonstrated by electro-myography that procedures that increased action potentials would produce pain, and conversely, those that diminished the potentials decreased the pain. Therefore they concluded that sustained contractions of skeletal muscles are the source of pain. Another factor responsible for the pinnacle pain could be a central unfold of the excitatory result of noxious stimulation of the soft tissues of the neck.

This unfold of pain is carried by the higher cervical nerves and could produce painful sensations within the forehead and face. Whether one or more of the above factors are responsible for the pain in muscle spasm remains to be determined. It’s been noted that painful spasms of the muscles of the neck and scalp could be mentioned the pinnacle and face. Two possibilities are prompt to elucidate the mechanism of the pain projection from the cervical spine to the pinnacle and face. One involves irritation of the descending or spinal root of the trigeminal nerve with transmission of pain to the pinnacle and face, and the other pertains to pain that is sympathetic, caused by reflex stimulation.

Tension headache could additionally be produced by discharge from the autonomic nervous system with resultant vascular distention and dilatation of the cranial blood vessels. In each instances, vascular and muscular changes stimulate afferent (pain) nerve endings and produce nerve impulses that pass along the afferent pathways to the central nervous system.

Diagnostic characteristics of tension headache include:
1. No prodromata.
2. Bilateral nature of the headache (commonly occipital and frontal).
3. Variability in character (burning-pressing-throbbing).
4. Variability in frequency and period (more constant than migraine).
5. Associated symptoms (numerous) as well as anxiety, nausea, and fatigue.
Tension headache must be differentiated from migraine and from headaches related to intracranial lesions, cervical disc disease, osteoarthritis, and spinal wire tumor. EPILEPSY. Occasionally epilepsy is confused with migraine, since visual hallucinations could constitute the professionaldromal symptoms of both. The loss of consciousness, rapidity of attack, clinical description, and positive electroencephalo-graphic findings, all facilitate to identify epilepsy.
