What is the role of CCSVI Venous Hypertension and proper/improved Cerebrospinal Blood flow?? #CCSVI #BloodFlowMatters TY DR CCSVI is definitely one of the causes of MS. The novelty for some years is that we are certain that, after studying at the La Sapienza University of Rome, there are 3 types of CCSVI: * a 1 type with patients suffering from an obstacle to the endovacular venous discharge, i.e. due to congenital or acquired anomalies that restrict and block the drainage of the investigated veins (jugular, vertebral, azygos) * a 2nd type with patients suffering from an extra-vascular venous obstruct8ion, i.e. due to external compression of the vessel * a 3 type with patients suffering from endo-vacular and extra-vascular venous obstruction So to simplify we can say that there is a CCSVI of the "hydraulic" type (1 type), a CCSVI of the "mechanical" type (2 type) and a "mixed" CCSVI of the two previous types (3 type), the 2 and the 3 type represent about 85% of cases. A patient with type 1 CCSVI will have a greater indication for angioplasty treatment, a patient with type 2 CCSVI will have a specific indication for specific physiotherapy decompressive treatment (RIMA Method), a patient with type 3 CCSVI it will have an indication for both an endo-vascular dilatation treatment and an extra-vascular decompression treatment. The RIMA Method devised by Dr. Domenico Ricci of Bari is able to release compressed veins throughout their course, as shown by a publication of June 2015 after a one-year study (Internal jugular Venous Compressione Syndrome: hemodynamic outcomes after cervical vertebral decompression manipulations-Pubmed).

The person reading my comment pls educate me if you know, My medical history are none except 2021-2022 I had ear nerve infection from the use of Bluetooth headphones and the first one got cured after I took antibiotics and my symptoms were as if a worm was crawling on the side of my ears underneath my skin, like a cold icy sensation or electric I thought I had myiasis and the second one I took different medication it didn’t work this time, the sensation is almost gone but it’s still there now it’s been months and I haven’t gone for recheck. Now the main question I wanna ask is so recently I’ve been getting headaches whenever I play for long hours and neck and back pains my posture is bad and I don’t know if I’m having a CSF leak 1. because of headache from using phone and bad posture 2. Because of a tapeworm cyst in my brain? I don’t get diarrhoea but these recent headaches and like a weird sensation like water trickles or same sensation as when I had the ear nerve infection before... We have 4 dogs at home and 1 dog got cured from worms , one (the mom)still has something which is a suspicion because something like a worm but not tapeworm came out and my mom saw tapeworms in the mother dog... Please whenever I get headaches because of overthinking my anxiety becomes high and every time I think it’s some kind of parasitic infection

I am not going to post my credentials on YT but trust me, that has nothing to do with your CSF. CSF can't be "heard". This is more likely simple "joint popping" that occurs in all joints (the cause of which is not clear, but may be sudden collapse of nitrogen bubbles), in your vertebral joints, which is harmless if painless

It took a while to figure this out.. but that is why it is a secret. This refers to bathing your brain with nutrients by inversion. Google Jim Carrey 33 vertebrae. I can run like a grasshopper and my attitude has improved. It really has changed my life. I do this 2x per day. And there are tricks to this practice. I have gained Height as a benefit. I will give you a hint.. your spine is a spring the foramen are meant to be open. Unless you subluxate daily or see chiropractic two to three times per week most likely your spine/spring is like a set of teeth that have never been brushed. Also you cannot get this brainwashing sitting Indian style squeezing and puckering yourself... Trust me it's like Arnold Schwarzenegger telling you to have a gallon of ice cream before your contest. They will not tell you the truth. I did find one video that describes the process of inversion and yoga benefits. Also you must break into this with baby steps otherwise you will get a disconnection. Rather you will pull muscles. This has happened twice when I have tried to force subluxation. So you want to take it easy only a few minutes at a time. Another hint you will be discouraged and you may feel nothing is happening. Do not give up. Everyone gains benefit. Your spine will stretch. You will be bathed in nutrients provided you are eating properly. Caffeine and being tense inhibits subluxation.
