My daughter, age 4, has been taking Singulair for a couple of months now. She has serious allergies and asthma, both of which seem to have been contained almost immediately. But, like the rest of you, she began experiencing odd issues. I didn't give them much thought until I saw all the postings today. The issues I have notices are: 1. Pain in her hip and joints. 2. Agitation, restlessness and aggressive behavior. 3. Inability to sleep. 4. Tiredness and fatigue. 5. Headaches. 6. Bruising. 7. Within the last few days, I noticed what appeared to be a mosquito bite, but just seems different. Will be talking to the doctor later today. Thank you all for your postings.
