Now having said that lets look at the word "dis-ease." I believe in taking a whole body approach meaning you don't just treat the symptoms of a problem. Find the root cause. The mind is a very powerful thing and the whole mind body connection is real. If you really break down the word disease you will know what I mean. Many of our health issues began in the mind. Have you ever tried aromatherapy using real therapeutic grade essential oils? Also, check into the possibility of thyroid dysfunction. There are a lot of alternative therapies that you could use instead of taking synthetic hormones for the management of thyroid dysfunction. A thyroid problem does many strange things to the body which could explain the brain fog. There is hair loss, weight gain, or weight loss etc. When your hormones are off balance your whole body is in a state of dysfunction.
Massage therapy can stimulate or inhibit the available levels of some endocrine chemicals. I know that exposing yourself to another human being is not something you are looking to do right now, but it's something you should look into. You could also self massage for the time being. Check out this new website ElevatedLife.net. It may provide you with some other useful resources such as brainwave therapy. Sounds expensive, but it's not. You should also check out the aromatherapy page to view which oils aid the symptoms you may have. Another neat thing you could try is performance taping like Kinesio Tape or try a Spider form SpiderTech. Taping can help with lymphedema which is another subject you should look into. Try a lymphatic spider from Spider Tech. Like the site says, There is usually not just one cure all but a series of simple things that does the trick. Explore the possibilities. Visit elevatedlife.net
