Why am I feeling pain starting from my left ear, through the neck, shoulders, left arm (mainly joints), fingers, back, left leg and all the way to the toes?

See a doctor and learn as much from them about your condition as possible.  There are several things that you can do to support your health and healing while reducing pain and symptoms. Nutrition - Get plenty of plant-based fiber, protein and oils.  Eat seeds, nuts and food with enzymes like pineapple, papaya and raw ginger.  Plant oils are good for you and cold pressed oils like sunflower seed oil or red palm fruit oil can provide nutrients that your body needs. Exercise - Get active every day.  Sweat and drink plenty of water.  You're helping your body to get any toxins out of your body. Internal Cleanliness - Reduce consumption of simple sugars, like bread, soda, candy etc.  Eat more vegetables.  Include live bacteria in your diet, such as found in yogurt, kefir. Rest - Exercising should help you to get tired and to have better sleep.  It's not always easy, I know, but get that sweat and hopefully get some better rest. There are many homeopathic remedies that can help, depending on what is specifically causing your problems.  Hopefully your doctor can help you determine whether it is related to bacteria, systemic yeasts or some specific nutrient deficiency.  Remedies Gelatin - One tablespoon per day of gelatin has been medically proven to help most people suffering from arthritis.  Purchase it in bulk and you should see some relief from pain within a week. Raw Ginger - Often difficult to obtain and to consume because of it's intense flavor and perishability, raw ginger contains enzymes that are very beneficial for people suffering from many maladies similar to yours.  I slice a small chunk into my morning smoothies and my arthritis has been improving after 32+ years of misery. Yogurt and Kefir - Lactic acid bacteria found in many fermented products are beneficial for your digestion and have been medically proven to fight depression more effectively then many medications.  Specifically, look for products that do not contain fillers, food coloring or added sugar, which often have only minimal live bacteria. Rosemary - Many common culinary herbs have beneficial effects including helping your digestive tract to stay healthy while reducing bacterial activity.  Other good herbs are oregano, thyme, parsley and sage.  This is one of the reasons that good chicken soup is often magic for improving people's health. Problems like yours can be caused by so many different factors, but most commonly, it's a bacteria, or a yeast that has gone systemic and must be fought off.  Medications can help, but it is up to you to do the real work of learning about it and fighting it off.  Don't feed it any more white sugar, whatever it is and build a healthy population of beneficial bacterias etc.Hoping for the best for you.

Good that you are checking your thyroid and have you been in any accidents, had any injuries in the past? You might want to try myofascial release, massage therapy, physical therapy, chiropractic, don't just live with it.You said this is going on for 4 years, what was going on in your life 4-5 years ago?

I came to this website as my wife is having the same problem. It started last year and we observed that the right side is also getting impacted. Conventional medicine was not able to detect anyhting except for asking us to go on with a lumbar tap at the time of attack. We then opt for a homeopathy last April 2015. We find it effective so far as the right side was able to recover, sagging on on her left face (similar to bells) no longer occur at the time of attack and lastly, her left arm and leg wwere able to recover it's strength as it was weaker compared to the right. The problem that is yet to address is to bring back the sensation on the left side. It's either weak or complete numbness .

Please get your full body check up some asap as it might be heart related . I don't want you to get worried about this but I've seen someone with the same situation. My friend's father in law was complaining for his lower jaw line paining and he was hiccuping since few days. After all the tests doctor suggested him for heart checkup and finally he was detected with 80%blockage in his heart. So please get it done.

I am suggesting few homeopathy medicines. Strictly follow what I am prescribing and do not overdo any medications, unless you discuss with me. Clear? You will get well in no time :) All medicines are to be taken in liquid doze only. Procure medicines from completely authentic shops and in factory packed condition only. No loose medicines and no pills are to be taken even if you know the vendor very well. Ideally take SBL, ADEL or Dr.Reckeweg brands. During the tenure of medication you have to completely avoid sniffing anything that may contain camphor, such as iodex, moov, Vicks cream or inhaler etc. You may consume coffee, however you may avoid the same if possible. Medicines may be consumed either before or after food giving a gap of thirty minutes. In case you are taking any allopathic medicines, which any way is not doing any good as per you, may be stopped. However if you wish you may continue taking those medicines as well. (Ideally don't take) If you have been consuming excess salt either in food or in savouries please reduce the intake immediately. Take one drop of conium 200c. Give a gap of one week and take Natrum muriaticum 30c one drop each morning afternoon and evening for five days consecutively. Give a gap of three days and take Natrum muriaticum 200c one drop in the evening only for three days. You would feel better the first week itself, however these medications will heal you.

i had the same problem, only difference being that my pain startes from half of my head through to the half side of my body and also that is was not continous, it occured 2-3 times a week and could have lasted for 24-36 hours. i was diagnosed with migraine and a type of cluster headache, while modern medicine has no effective treatment other than pain killers, natural remedies, homeopathy and yoga combined with few dietery restrictions helped me a lot, so hopefully you should also get benefit from these.
