Hi, Jockette,
I am sensitive to some adhesives and not to others. My PT used one kind of tape the first time (no problem; kept it on for 4 days); and a different kind/color the second and third times. The second time, with the different kind of tape, I took it off the day after she applied it, due to itchiness; and the third time, I took it off during a massage right after therapy--it was so bothersome. For me this is consistent with how my sensitivity builds up with certain substances. So....what's my point for you? Well, you are likely to continue taping because it is helping you. Monitor whether or not the itchiness develops again, and whether or not you get increased redness around or under the tape. If you get itchy again, especially if the itching increases or the time of wearing decreases due to the itching, then you may want to try a different brand of tape. Sensitivity can develop over time.
