I just took a TB test about 3 days ago. Right after my test, I noticed my arm felt funny. I figured after any shot your arm will feel a little weird. During these past 3 days, I have still felt this weird feeling. It started at the area the shot was given and moved up to my bicep. My arm is sensitive, somewhat weak, stiff, and it feels pressured (like when you use the inflating arm band to check your blood pressure.) I have had no other side effects.
