I noticed a bump on my shoulder near my collarbone recently. It felt like a knob on my bone, about half the size of a marble. It showed up suddenly, and I have been trying really hard not to freak out. I asked my husband to feel, to see if he noticed, and right away he said WTF is that! I finally got to the doctor. They did an x-ray. It's just arthritis. I was afraid of bone cancer! BTW, I have good insurance as a public employee and didn't pay a dime for the visit or the x-ray. I picked up a prescription on the way out. Grand total: $10, including parking. No one should have to put off going to the doctor in a case like this, and no one should have to face a huge medical bill. On top of Medicare for All, we need someone who will take on the prescription drug companies. An HIV prevention drug that is 2k here is $8 in Australia. Almost half of people on insulin ration their meds. It's obscene, and people die because of it.
