Hello, I'm writing because I'm very stressed out and I've found this board very comforting in the past. I just had a TB skin test today, and now there's a slight red swelling. I don't feel too ill, but my chest does hurt a little. It was supposed to be chest wall pain or pleurisy--I had a pneumothorax a couple of months ago. My IBS has gotten much worse. Can the patch of skin swell up if you don't have TB? Like if the nurse gave you the shot more shallowly than usual, as she mentioned? Also, does anyone have any suggestions for calming the nerves, beesides valium? Thank you so much.Shauna
