There are a few things that can be causing the hand issues. I have Raynaud's which is a nerve syndrome that affects my fingers and toes. I also have osteoarthritis, and mild carpal tunnel. Great Combination of disorders that affect my hands. Typically my right hand is affected more than my left, but both will go numb sometimes without much warning, or while doing things I was used to doing. The Raynaud's will actually make my fingertips and toes turn bluish when I am introduced to a climate that is cooler than the previous one, and when I am introduced to a warmer climate they turn an evil red color and start this painful burning tingling sensations. Unfortunately the only thing that seems to help is putting on gloves sometimes, especially when I am going into the freezer. That or compression gloves which are not only recommended for arthritis but some help alleviate the issues associated with Carpal Tunnel. I always joke that I am too young to be falling apart this much, and honestly feel like I am the warning symptoms listed on most medications when I list off all the problems that I have. I have also had it brought to my attention that I need to get tested for Lyme's Disease as it is the great imitator and can mimic several diseases and disorders...some of the effects are irreversible. I know for sure that at the moment mine is probably due to sinus pressure either related to allergies or an infection and possibly and infection in my ears...the only reason I state this is because of the pain, and the complete tiredness and the agony of having to do something besides sleep.
If you have high blood pressure, you should see a doctor about getting put on medication, and also let him know about the thumping in your ear you are experiencing and how it happens when your heart is beating hard. He may want to run further tests because it could actually be something causing pressure on an artery or vein near the eardrum. While the fan may seem to work, it could be mostly because it causes a relaxing type of state within you which can lower a person blood pressure if it is caused by stress. Just because the fan works, doesn't mean that it isn't hiding or masking a serious problem.
You will want to get a mouth guard if you are grinding your teeth at night. While you may think you have your TMJ aligned, teeth grinding can cause it to "flare" up. TMJ can also cause your jaw to shift and rest on your ear canal. It doesn't have to happen on both sides. my mother had it happen just to her right. It actually started causing her to lose her hearing because of the pressure it had been putting on it for years had basically crushed her canal to a small tube. You may want to ask your doctor who you should see about having xrays performed on your jaw to determine if your jaw has shifted on the left side. The sound you are describing is the same sound and feeling my mother had for years and it progressively got worse. It wasn't until she noticed a slight hearing loss that the doctor took her seriously and had it checked out. Unfortunately because they waited so long, most of the hearing that she lost she will not get back. You seriously should have the TMJ looked into, and Seriously get a mouth guard for grinding teeth while sleeping. It can also be what is causing the pain in your neck and tightness when you get up in the morning...if you are grinding those muscles are working all night...
Your's sounds more like the tube in the ear being pressed by something causing it to not be able to drain properly. Once the ears drain correctly the feeling goes away, and your symptoms will be alleviated. Unfortunately if there is something wrong with that tube, and it doesn't right itself...surgery is typically the next response.
My mother has TMJ, she actually had to have her jaw broken and rewired because her jaw had slipped and was putting pressure on her right ear canal. The problem you had with your hearing is the same problem she was having. And even after it has been fixed, she still has issues hearing out of her right ear.
Certain Minerals and Vitamins are only recommended in a specific amount for you age, weight, etc. If you are taking too much of certain ones, instead of your body disposing of them like normal, it can actually start to poison you. You may want to look into...especially since Magnesium is used in part by your body to regulate blood pressure. If it is causing adverse effects due to having too much, it could be the pulsing of blood going through a vein or artery near your eardrum that is causing pressure and making the eardrum pound/vibrate. Plus if there is anyway the makings of the area around your eardrum are putting pressure on the vein or artery near the eardrum, it is possible that is the vibrating sound you are hearing, and why when you turn your head to the left it goes away, weakens when looking straight ahead, and then gets worse when you are looking to the right. The pressures is lessened when you are turning your head allowing the blood to flow smoothly. Which is another possibility. I would seriously ask my doctor if either of these are something they could look into for me, or send me to have testing done for. Are you experiencing any pain with it, or is it just vibrating? With Pain there are added risks...such as an aneurysm or an earache. (Not all aneurysms are lethal, unless they are ignored and rupture. My dad actually had three, but they were in his chest not brain. So they were able to put a stint in to correct two of them, one of them kind of mended itself...which is good since the location was where they could not fix it. But you should discuss all of this with your doctor. Because if it is something causing pressure only on the right side, there are other things that could be...but I don't want to scare you. So best to ask your doctor to test for magnesium poisoning, infection, and ask if there is something causing pressure on either a vein or artery near your eardrum, that is alleviated by turning your head to the left. Hope this helps some.
