Lantus and travels

I have been on Lantus for about a month and I started having leg cramping on both legs which is really driving me crazy. It starts at the thigh area and travels down the whole leg. It feels like the beginning signs when one gets a Charlie horse. It is not letting me sleep at night. No matter what position I try to sleep.

I HAVE BEEN ON LANTUS FOR A MONTH AND A HALF. MY SISTER HAS BEEN ON IT FOR 3 OR MORE MONTHS. WE BOTH HAVE THIS SHARP PAIN ON THE RIGHT SIDE OF OUR SCOLDER BLADE. I JUST WANTED
TO KNOW IF ANY OTHER PERSON HAS THIS PROBLEM.
MANY THANKS

My wife began using Lantus approximately 2 weeks ago
(11/21/05). Very early on Thanksgiving Morning, she
awoke with her heart skipping beats. She had not experienced this before the Lantus injections. We wound up
at the ER at the local hospital on Thanksgiving morning in
Cranford, New Jersey. The Chief of the ER was on duty and
after hours of blood tests and being hooked up to an EKG,
he told my wife to immediately discontinue the Lantus
injections and return to Novilin 70/30. However today is
12/05/05 and her pulse is still erratic at times.
Has anyone experienced problems with their heart rate
while using this medication? Please let me know.
Thank you!!!
