Why so pain?

Do you know why it was so painful the first time my hubby administered the jab? He actually did not insert the needle fully into my bum bum!! He only inserted 3/4 of the needle in! That explains the painful after effects! Imagine my bum bum was in pain for the entire day!

Today, its much better... but I still notice that there are air gaps in the syringe after extracting the medicine. Huh, must improve this aspect for the next injection on Fri... and gosh, the needle is really thick!
