Singulair and m 46

I'm 46 yr old female and have been taking Singulair for 5-7yrs. I have been treated for Asthma for the last 10 years. I was treated at first with pulmacort until I figured out it was causing a break out around my mouth after several years (4) of being on it. My Dr. switched me to Singulair. I never noticed any of these side effects, until after I've read some of yours. I work out 5 days a week( swim & cardio) and have noticed my ears sometimes bother me. I'm on the computer all day, but my right hand has some tingling occasionally and sometimes it's a conscious effort to open and close my hands. I went to this web site to find out the long term effects of this drug. I had my blood pressure taken today and normally it's around 100/60-70 and today it was 100/80. I know that's not terribly high, but for me it is. I only take two drugs nexium and singulair and was wondering if one could be causing a rise in my blood pressure. If anyone knows please advise. Thanks Sylvia
