Insulin pump

Hi frens.... Sorry for not being in tch for long.... was busy in office. This time my concern is insulin pump... you mite think tat i am out of this world or i am ignorant of the things going on around me but to be true I dont know at all about such pumps.... and tat is because in my country its not available and if it is available then its very rare to find..... how does it work and does it really help?? Its been quiet some time now tat my levels are above par.... so m bit worried and want to device something out of this..... If someone from India know where do we get these pumps pls do inform... and please ppl let me know about the effects and side effects... it will be grt....
