Acai juice symptoms and conditions

My daughter is 6 and has been on singulair for 2 years. Anytime we miss a pill she ends up with a fever of about 100 and is exhausted. Within a couple of days of her medicine it's gone again. The doctors think it's a complete coincidence but I don't agree.

I had a viral infection and was put on Levaquin 750 mg. After being on it for 5 days my joints began to hurt. I didn't think the medicine caused it and I continued to take it. Until the 7th day I began to research and found this web site. I quit taking it. I was unable to stoop down and it hurt really bad to walk up or down stairs. Regular walking was some painful. I also had some pain in my wrist. I've been off the medicine for 6 or 7 weeks and I'm still having bad joint pain in my knees. I'm unable to perform normal activities. I'm not saying Levaquin caused it; but it's just that when this started was while on it. If anyone knows how long this might last or if it causes permanent damage, please let me know! I will be going to a specialist in 1 week to get this checked.
