Hello Smiling Cosmos,
Cute name for a handle. As to your situation.
Interesting how lumps and spasms show up in our life's. There was a time in my life when I use to have many muscle spasms and a few lumps in my legs. Especially spasms in my calves. Wow. Did they ever hurt... During that time of my life I was experiencing an excessive amount of stress and my overall health was not so good.
I looked inward for a solution because I wasn't getting any from the medical community. Drugs just did not solve anything. In that process I discovered many things about myself in the way of patterns of behavior that was unconscious until I became aware of them. So I began to meditate and do forms of de-stressing exercise - Tia Chi, Yoga, Qigong.
What I discovered about myself was truly an awareness of who I am is not my body. When this started to sink into my thick skull my entire life changed. I lost weight, I began to eat a much healthier diet for my body's blood type. I paid much closer attention to balancing and harmonizing my immediate environment. My relationships with others altered as well.
The point to all this is the spasms and lumps just disappeared. I had given up the notion that I needed to know 'WHY' they where occurring. I did not find the answer to my health issues in my mind... My heart knew exactly what to do.
Stress is, in my view, the # one cause of all illness, dis-ease and death in the world. So... Find ways to remove the accumulation of stress in your body. Practicing Qigong daily is one of the best ways to do just that. Here is a link to a form of Qigong Exercise that you can learn that is simple to do. This website has videos of 5 easy to learn Qigong exercises that can rapidly alter your life for the better... Love and Light... Gary
