My doctor provided and recommended these needles for a short term injectable treatment. As someone who has never used needles before, I was a little nervous and apprehensive. After just a few pins, these became second nature for me. They truly were as comfortable as a needle could be. As long as the alcohol wipe had dried and I had good technique, I did not feel a thing. I would absolutely recommend these to anyone nervous about giving themselves a needle. They are so short and they do not hurt.
