Hi, Thanks for using the HCM.
Skin test for TB its a purified protein derivative of M. tuberculosis
Test should be performed by injecting into with in skin layers , means intradermally.
if it is injected deeper in skin, subcutaneous layers can cause swelling and infection in that area.
continue antibiotic treatment.... slowly it should come down , swelling should reduce in size & all inflammatory signs should come down....
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon....
