Hello and hope you are doing well.
The rash you are refering too could be the PPD test. It could be positive due to an old or recent infection. It could also be due to BCG vaccination for tuberculosis. This is correlated with clinical symptoms and blood tests, which will show a raised ESR and increased lymphocyte count, if it is an active infection. So, don't worry and you can post any further queries you have, will be glad to answer.
Hope this helped and do keep us posted.
