If i have an overdriven sympathetic nervous system (manifesting in tachycardia &restlessness) would that be a cause of my muscle rigidity? Sooo tight
Possibly: Your system is in a high strung state and could cause muscle tightness and tension. I assume you have had endocrinology testing to rule out hyperthyroidism,pheochromocytoma,etc. If so, perhaps a stress management program would effectively treat your symptoms best and you have been recommended to avoid alcohol,caffeine and nicotine. Your physician would know best whether beta blockers would help. ...Read more

Pilo erectors: Goose bumps are caused by activation of the sympathetic nervous system which secretes Adrenalin (fight or flight reaction) which causes the tiny muscles to raise hair follicles temporarily. Cold temperatures can also do this. ...Read more
How does Norepinephrin block pain in the Cns?Docs say i have an overactive sympathetic nervous system?Would nortriptyline create more symp cns problms
Neurotransmitters: This is a very complex question, and you need to discuss this in detail with your treating physicians. Both Norepinephrine and serotonin act on the dorsal horns of the spinal cord to inhibit excessive transmission of nerve cell fibers, thereby decreasing the central (brain) perception of pain. Nortriptyline should not worsen that, and may help some. The SNRI's medications help with pain relief. ...Read moreSee 1 more doctor answer

Mostly peripheral: Cranial nerves have their cell bodies within the central nervous system (cns), but the majority of their length/"processes" are outside the confines of the cns. The myelin covering nerves inside, vs. Outside, the CNS is different, and cranial nerves are subject to disorders common to peripheral nerves.

Why does the heart have a separate circulatory system and what circulatory system is effected by a heart attack?
The heart: doesn't have a circulatory system that is truly separate,but it is a muscle, and like any muscle or organ,has its own blood supply derived from the main circulatory system.The coronary arteries extend from the aorta and supply the heart. In a heart attack,one or more coronary arteries become narrowed or blocked, and without enough oxygenated blood(ischemia), the supplied tissue may die(infarct) ...Read moreSee 1 more doctor answer

Do people with chickenpox from a cranial nerve get protection from zostavax? I read CNS was sequestered from the immune system.
Zostavax is protect: You need to clarify this question with your physician. Zostavax can help prevent herpes Auster and postherpetic neuropathy. It is not 100% protection but it's better than not having any protection. There will also be a new shingles vaccine which is not live virus coming out next year. These are certainly issues you can discuss with your physician about. ...Read more
