I began Incruse inhaler 12 days ago, added to Breo which I have been taking for 8 months, in an effort to reduce extreme mucous. I am a 62 year old female severe fibromyalgia but no other health issues. All other vitals are outstanding nding for my age and (over)weight. Yesterday and today I ve had severe muscle spasms/cramps in my fingers. ; very sharp pains, when using my hands for things that don t take exertion, such as turning on a turn signal when driving. I m also retaining a lot of fluids, but not as concerned about that. Could Incruse be causing this?
