Muscle Spasms
When I had this, I thought it was tumors. Actually, for me, it was muscle spasms. What resolved it for me was dolomite to bowel tolerance. Two tablets in AM and two in PM to start, then increase one at a time to the dose that eases your pain or gives your diarrhea. You can also chew a few of the tablets when you are in the middle of a spasm and it will take away the pain right away. It also helps not to drink soda as the phosphorus pulls the calcium out of the bones.
The cheapest place to order dolomite is Puritan's Pride. You may be able to substitute a calcium magnesium supplement at first, but I have not had good results with this.
If this works for you, try to increase your intake of mineral rich foods, such as kale, collards, mustard greens, etc, also
Sea Salt and blackstrap molasses.
Dolomite is quite controversial since it comes from limestone, not from plants, but in the meantime, it is the most effective solution for your "lumps."
I urge you to try this right away. When your body has gotten so mineral depleted that it has to pull the minerals out of the bones and muscles, it is in bad shape. The body will always try to protect the brain and the heart first, so you need a lot of minerals so that your whole body will have them.
You don't want to do any cleansing until you get this taken care of, IMO that will only make your problem worse.
