New clothes can definitely cause irritation. I also get red bumps on my thighs and hips--my doctor said in the winter it is from dry skin, and in the summer from moist skin (it's worse after I work out and if I don't dry off completely before getting dressed). Your blood work can be trusted, but it could still be a dermatological issue like irritation or a fungal or yeast infection--nothing serious, and certainly treatable.

This is a great thing to take to T. With her you can work through some of the anxiety and also decide at what point something odd becomes something you need to see a doctor about. Do you have a friend who knows about your anxiety? My close friend and I Google for each other's anxieties. I search for health/cancer info and pediatric issues for her, and she searches for crime/safety for me. That way we don't get trapped in that Google Panic.
