I had a flu shot and a tb test last week on Tues, on Friday I started to notice a weird feeling on my tongue . It is sort of a numb, non tingling feeling and is noticeable on the left side. Also, the feeling now includes the left side of my lips . I am a 38yo male and have no other signs or symptoms. Could this be an allergic reaction from either injections? The tb test was red and indurated. The first tb test I ever had was negative (over 10yrs ago), the second was positive, the third was negative, and this recent one was positive. I have read that you can have an allergic reaction to certain manufacturers and is why it was positive the second time. Thank you.
