I swell up under my jaw on the left when I have the smallest amount of lactose but I am not allergic according to the food allergy blood test and the docs say that nothing is wrong even when I physically show evidence that something unknown is wrong. What could it be? Then I also have a knot on the back of my neck on the left the side of a pea. Both of these problems are painless. Yesterday I noticed a weird pain/tension in my right underarm but I assume its from sleeping on my arm wrong, and there is no swelling for this pain that I can notice. What type of infection could it be? I don't have any fever so its not valley fever I assume..and I worry about cancer though it wouldn't make sense since no family history of such. I have a good thyroid, no std, no diabetes, no high cholesterol, and the only abnormal thing that the blood tests showed was a liver with a little extra fat but the doc said it didn't look bad but to watch it....I have acid reflux or heart burn that I never got diagnosed but I know I have. So what's wrong with my health, whats the illness?
