Neck stingers/burners?
Other than the dizziness, what you are describing sounds like some pinched nerves in your neck. The suboccipital nerves carry sensation from the back of your neck up to the top of the back of your head. If these are pinched or squeezed, the sensation feels like a jolt over this area, similar to how hitting your funny bone (your ulnar nerve) results in a jolt down to your little finger. Unfortunately, these nerves come out in a VERY tight area with lots of muscles going in lots of directions. Any swelling in any of these muscles from a sprain can result in those nerves being pinched. It is not clear where the dizziness comes from, though. If this continues, you will definitely want to discuss this with your doctor. If it is just the zinging that continues, taking advil, ibuprofen, or any NSAID regularly for the next couple of weeks will help keep the inflammation down until it heals. As always, discuss these and any questions with your doctor.
Do stingrays really like to be touched/petted?
I just went to the Oklahoma Aquarium and the stingrays in the petting pool went up to you (some even climbed on the rock to be petted). I also saw a video on YouTube where people stood on waist-high water in the ocean off of Tahiti and wild stingrays came up to them like puppies. (I know what happened to Steve Irwin and I feel that was a freak accident. I feel if the stingray saw him and knew he was not a threat, then the stingray would not have done what he did.)
When I crack my neck, I get a warm tingling sensation down the right side of my arm. What does that mean?
If you get the tingling on the same side as the “crack” (cavitation) then it means the accessory joint movements in the facet (Zygaphophyseal) joints on that side of the neck has now increased and the nerves (Cervical 4–7) that flow out to the hands (median, ulnar and Radial nerves) from that side are sensing this change of tension inside the intervertebral foramen.Nerves can sense the smallest changes (they are chemosensitive and mechanosensitive) and sometimes very tight/ overactive muscles and joints could be irritating/ reducing the blood flow to the nerves (via vasa nervorum) and such an increase in the facet joint movement could potentially increase in the blood flowing into the nerves and cause this “warm fuzzy tingly sensation”. This is a desirable sensation.However, in some necks IF there is a reduced area/ space for the nerve exiting the foramen into the upper extremity because of a Disc injury/ prolapse or Osteophytes or other occlusions the nerve can be badly irritated during a quick “crack”/ adjustment/ cavitation and the sensation will be sharp and shooting more closer to an electric shock. This is a non-desirable sensation.
Electric shock feeling when stretching arms?
so I get this feeling in my hands and fingers as I stretch my arms out straight like I'm being mildly shocked. Is it a normal feeling due to maybe be being not flexible or something more serious?
Is it possible to create a jet engine system with a cold exhaust or by-product....?
In order to propel itself, an airplane needs to expend energy. And no matter how carefully done, this incurs a raise in overall entropy. To get some air to move faster than the environment creates eddies on the boundary of the jet flow, and those eddies will dissipate by raising the temperature. Every form of energy will eventually dissipate in heat. So, the short answer to your question is: no, unfortunately. The laws of physics do not allow for perfectly cold energy. What you can do is dissipate the heat over a larger volume so that the exhaust plume is bigger but colder overall (but still contains the same amount of waste heat. Stealth aircraft use that technology to reduce their infra red signature (a bigger plume that is not as bright in infra red is more easily missed than a very bright tiny one -- one can easily spot a star in the night sky, but the same amount of light over a larger area is very hard to distinguish -- explaining why flares can be used to distract an incoming missile).
My cat's an idiot should I take him to the vet?
I love my cat, I really do, he's a sweetie. Whenever i'm sick he lays with me, never leaves my side. But there are times were I wonder if he doesn't have some kind of feline mental retardation. Today I was cooking some hamburger meat on the stove, the meat was finished and I turned the stove all the way to high (electric burner high) to melt some cheese on top, I turned for a few seconds to make sure my toddler wasn't in the kitchen when I hear the most horrible blood curtailing scream (it really did sound like a woman) it was my cat, he jumped on the stove (first time he ever did this) knocked the pan of food to the floor and landed on the read hot burner for about a second before he jumped and hit his head on the exhaust fan and fell to the floor. I looked at his paw and the hair around it is burned and there looks to be a 2nd degree burn on the bottom of his front right paw and 1st degree burns on his two back feet. I'm not sure if I should take him into the vet, he's a in door cat so I don't think he will need to worry about contamination, I put a little aloe and a bandage on his feet and I put his kitty slippers on him (cute little suede shoes for cats), but I don't know if I should take him to the vet , what do you think?
