Issues focus symptoms and conditions

I have been on lisinopril for over 3 years - 5 mg/day. I am a 52 year old female in great shape and exercise daily. For over a year now I have had muscle aches, muscle weakness, heart palpitations, foggy brain feeling, insomnia, fatigue, some tingling in extremities. I also sometimes get these spells where all these symptoms come on at once. It's very strange. Been to numerous doctors including, PCP, 2 neurologists and a rheumatologist and after many tests they all come up with nothing. After reading posts at this site I think it may be the Lisinopril and with my PCP's permission stopped taking it 11 days ago. My blood pressure is fine - I am monitoring it daily. My symptoms still remain. Does anyone know how long these symptoms may continue? I am grateful for any additional information you could provide.

My daughter will be 2 in June and she suffers with asthma she has been taken diff meds such as xopenex, pulmicort, orapred, and now singulair. i researched all the other meds and took her off but the asthma specialist said she needed the pulmicort and i asked her pediatrician what he thought and he prescribed singulair he said it was completely safe and i had nothing to worry about but now i am very much worried because my daughter is only 21 months old and can not tell me exactly what wrong if anything. she has only been taking this singulair since last night so it has been twice she has taken it and last night she had a nightmare. she was fussy going to bed, it took a long while to wind her down she normally falls asleep between 9 and 10 pm last night she went out around 12. her lungs r very sensitive and i want her to get better but a lot of these meds have really bad side affects and who's to say what will be the long term affects and thats what i worry about the most. i just don't know what to do and I'm very worried. i came across this site by accident but I'm glad i did cuz now i know that this is not safe to give my 21 month old daughter.
