"Perfect Storm" of breathing issues

I have a 'perfect storm' of breathing issues and could use some advice.  Panic, asthma (sort of), allergies, GERD, polyps.

Follwoing my first panic attack (couple months ago) my GP, just to be on the safe side, put me through a series of tests to rule out anything catastrophic.  A pulmonary functions test showed some slight asthma perhaps during a broncho challenge.  My GP put me on Singulair.  I take it as directed, but I think it's giving me muscle and joint pain in my arms and legs; something I never had before.  

I took the results to my allergist who said it wasn't clinical asthma.  The test suggested more a air way sensitivity as opposed to full blown asthma.  Said staying on Singulair is good though because it will help my sinuses through allergy time (9 months a year where I live) He also chastised me for going off my Nasonex (I'm back on now).


To be frank, I can't afford the medications to treat ALL this stuff.  I'm thinking of taking out the Singulair (still staying on Prilosec, Nasonex, bi weekly therapy and OTC anti-histamines).  My theory is, if I don't have asthma (my baseline lung capacity is good, and even at Level 5 broncho challenge, I didn't feel nearly the level of breathlessness I did while panicking or after a heavy mesl) why should I take the Singulair?  It's expensive and causes me muscle ache apparently.  I can still address allery based symptoms with the Nasonex and the anti histamine.  Does anyone else think this is out of line?
