Common reaction to the pruified protein derivative that be injected just underneath your skin. Don't scratch or rub. Take Benadryl.
MiNE iTCHED TOO BUT iT GOEs AWAY..MAiBE YOU SHOULD WAiT AND iF iT DOESNT GO AWAY iN A COUPLE MORE DAYs THEN GO TO YOUR DOCTOR..DONT WORRY YOU'LL BE FiNE..GOODLUCK..
No, it does not. It's not unusual for it to itch. The size of the bump within three days will tell you if you've possibly be exposed to TB, not necessarily that you have TB disease. Go put a bet on and see a nurse three days from the time you got the check.
Check with your doc. No, it doesn't suggest that you have TB.
