I just had my second treatment this week. First treatment in July. After the first treatment, I had swelling and tenderness, a little numbness. There were lumps in my armpits for 6 weeks but have since resolved. I stopped sweating immediately after the first treatment. Some sweating did come back after the first treatment, though nowhere near as bad as it had originally been. Because I was sweating, I opted for level 5 treatment for the second procedure. I was more swollen and had more pain the second time around, but only lasted a few days. I no longer have odor and don't need to use deodorant. Also, I have had a significant decrease in the amount of hair growth in my armpits, bonus! I would definitely recommend doing this procedure. I do not need to wear 5 shirts anymore to mask my sweating and can wear tank tops without being embarrassed.
