This is an important topic. I have been practicing mindfulness almost constantly during my daily life. Not a disciplined practice, but just to experience and enjoy life wherever I am. It is simple to describe, and easy for me to say. For me, it is to focus my senses on something, anything, in the world around me without any attention to thoughts, naming of things, or judging. One is in total acceptance; no resistance, to trying to separate one's self from anything. Then one is in their inherent state of peace, contentment, unconditional love (which is total acceptance). Everything in the world is seen as beautiful, and connected in unity.
I became afflicted with a burning foot nine months ago. Also sharp jabbing pains. Doctors diagnosed it as peripheral neuropathy, and complex regional pain syndrome (RSD). My foot became red and blotchy when lowered to the ground, and more painful. It became warm, and a vascular doctor agreed that there was blood filling the skin capillaries. This sounds to me more like EM, as CRPS usually has cold feet, that want to be kept warm, and begins from an injury, which I didn't have. However, my case has some differences from typical EM. My foot gets more painful in cold water, and warm water. It is most comfortable in water at 80 degrees.
I have been studying my pain with mindfulness, and found I became more aware of the pain. However, I had more of the sense that it was not happening to my essential self, but to my body, which I was experiencing. In this way, the pain has not affected my peace of mind, or happiness. The problem and its pain has not gone away, in fact, it has intensified in the last month or two, and is trying to spread up my leg to the knee, and some symptoms are showing up in the left foot. I can not walk more than a few steps on the right foot, and my mobility has been seriously impaired. I feel this is a challenge to me, to maintain my positive attitude and disposition no matter what comes of this. I do not feel sorry for myself, but am grateful for a wonderful life full of challenges and learning. I love to be with people and inspire them, If I can. I am involved with spiritual groups and have contributed to them from my knowledge.
