First question: yep, first T shot was the sorest (lingering soreness, ~3 days). That lingering soreness mostly stopped after the first 3 or so shots. I occasionally get sore from shots now, but it doesn't last nearly as long, nor is it as sore as those first few shots. I shoot weekly.
Second question: all the time. That is my #1 reaction from people. If I tell them that underlying psychological causes have been ruled out, the response is "well, you're just confused." If I show them literature backing it up, then "the doctors are quacks." There are times when no amount of reasoning or logic will prevail...
