solid bumps

I had an outbreak of bumps on my right elbow when I was sick. Most of them went away as I got better, although I'm not 100% healthy - more on that later. The biggest bump is the size of a pea and has stayed since the initial outbreak 2 months ago, although it is slowly dropping in size. It is painful to the touch, has a white core, and is solid. It isn't pus.

Right before the bumps broke out on the right elbow, I was coughing hard enough to push a "line" of pain from my clavicle/shoulder to the right elbow for every cough. People who saw me at my worst said I was white. I can feel the "path" of pain in my my arm come and go often, only now it is a lessened, softened version.

The symptoms I had at the time of the coughing were amplified from pollen allergies. I've also a sensitive site near the lower colon that can swell and form a cyst if my diet strays from raw, natural foods for more than a day. My understanding is these symptoms, as are all symptoms, a sign of congested organs, so the solution is to cleanse the organs. I'm not sure which way to cleanse, as there are so many options (analysis paralysis), but I've looked closely at Dr. Schultz's cleansing products.

I'm looking for two things:

1) cleansing options (clark, schultz, master, etc)
2) what the body did to create this new ailment
