I received my second treatment of Vanquish and worked out at gym afterwards. The next day, I experienced swelling, stomach soreness, shooting sharp pain to rt lower side od abdomen, pins and needle hypersensitive sensation over while stomach area. I called my doctor and he said take Motrin and apply moist heat but made it feel worst. I called him after 5 days with no change and same symptoms and said to wait another week before next treatment and add ultrasound to aid in reducing soreness and swelling.
