My son started taking Singulair in Oct.2012, and then he started
complaining about his leg, some kind of weird sensation. He called itchy feeling, but it was something he could not scratch away, something underneath the skin. He kept asking me to punch his leg with a 5-pound dumbbell. He wakes up twice or three times per night. He puts some hard things under his leg, and put press on it. He does it almost every night. He can't get enough sleep.
