A few months ago my doctore changed my medication from Carvedilol to Nifedipine due to Raynaud s Syndrome. Since then my right ear has had congestion, ringing, sinus issues on right side and voice change, like I was coming down with a cold. These are rare side effects that I have found on some websites. I mentioned this to her on June 13 but feel it was ignored. It may have been notated in my records but I was never checked or asked anything about these problems. I would like for these problems to cease. Anything I can do to resolve them like an antihistimine or decongestant? Or should medication be changed to another calcium blocker? I have tried peroxide, baby oil, everything I could online to open ear back up. It may stay blocked for a few days, 2-3 weeks, then open up for some time and then block again. Thank you in advance!
