The delivery is very fast. I accidentally twisted my waist when I was working. I felt pain when I bent over. Every day I had to do housework with a mischievous child. I couldn’t stand it for a few days. I went to sleep at night and it hard for me to fall asleep. It is not convenient to go to the pharmacy, so I decided to buy medicine online, I want to get it within four days, but it only needs 3 days. In the evening, I used it. Now I feel better, but I still have to rely on it.
