I know this will sound weird but a cold shower helped me. I think mine was caused by my lymph nodes pushing on my ear. I also go headaches.
Now I stand and swing my arms a few times. Our lymph system does not have a pump like our circulatory system does (heart). In order to get lymph to move we have to move or massage.
Remember that stress can cause a lot of symptoms and that is the hardest thing for us to handle. How do we not get stress especially when we know it is going to hurt and be painful?
So as best you can try and not worry.... so easy to type and hard to do, I know.
In case it is your lymph, here is the awesome massage that I do. Only she suggests doing it 50 times and to start, I would only do 10 and slowly work up to 50 in a week or so.
