DEAR DR. ROACH: How reliable are home COVID-19 tests? I've read one article that said that if you tested negative you could be certain that you did not have COVID-19, but if you tested positive there was a significant chance of a false positive.

DEAR DR. ROACH: I am told by doctors that the natural immunity your body develops by having had the COVID-19-19 virus is just as, or even more, effective at protecting you as one of the three vaccines that you are pushing people to get.

DEAR DR. ROACH: I have sciatic pain. I do my best to mitigate the pain with exercise. The only painkiller I can tolerate is aspirin. I have been approved for physical therapy, but that doesn't start for another six weeks. When I stand up, the pain is intense, and I just force myself to walk, because then it goes away. My blood pressure is now ...Read more
DEAR DR. ROACH: Does our skin make vitamin D from sun exposure through a car's windshield? Sometimes I expose my stomach for about 10 minutes while driving or riding in a car, but I'm not sure if the skin responds the same way through glass as it does with direct sun exposure. -- S.R.
ANSWER: Sunlight allows our skin to convert 7-...Read more

DEAR DR. ROACH: I belong to a garden club that meets in a local indoor hall. We have one member who has been driving herself crazy worrying about COVID-19. She wants us to meet outdoors even in the winter, because she says we can't be sure the building is clean enough and we don't know the status of others who may have used the building while we...Read more
DEAR DR. ROACH: I watch a lot of skin-care videos by dermatologists. Sometimes they will have a patient who has a very infected and inflamed blackhead, boil or cyst, etc. It seems like the main treatment is oral antibiotics. My question is: How come we don't inject antibiotics into infected areas like this? Why do we take them by mouth or IV? ...Read more

DEAR DR. ROACH: You recently replied to a question regarding vaccination among health care workers by saying "they are ethically obligated to get the vaccine in order not to infect their patients."

DEAR DR. ROACH: Now that working from home has become very commonplace, I've noticed a lot of people raving about posture correcting devices.

DEAR DR. ROACH: I am a 75-year-old female suffering with very painful "end-stage, bone on bone" osteoarthritis with bone spurs of both shoulders and rotator cuff damage (tendonitis).
