I'm really worried because my wife has had a lump in her right armpit for about three months, and now there's swelling in her right breast too. Her doctor had her do a PPD TB skin test, and it came back positive with a 20 mm induration, even though she doesn't have any typical symptoms like a cough or fever. She's on anti-TB meds now, but I'm wondering if TB could really be causing the lump and the swelling. Is the skin test enough to confirm TB, or should we look into doing more tests? Your advice would be really helpful.
yes tuberculosis can cause lump. skin test is a initial diagnostic test

I'm trying to understand if a CT value of 31 means someone is still contagious for Covid after 14 days. The person feels great now and even had their loss of smell come back, but this CT value is 31 on their second test. Is this something to be concerned about?
A CT value of 31 is on the higher end of moderate, meaning the viral load may be low enough that the person is less likely to transmit the virus, especially if they have recovered symptoms like the return of smell.
