My wife has had a loud pounding in her ears at various times over the past several months. T he pounding usually starts in the early evening and goes on for several hours until bed time. She is a diabetic and takes oral medication as well as insulin. At 4pm she takes medications and vitamins. The pounding usually starts around 6 to 7pm. The meds that she takes at 4pm are Norvasc-10mg, potassium/ magnesium- 99/500mg, vitamin D3-2000 mg, probinicid/colchicine- .5mg, multi vitamin-Centrum Silver. Noises aggravate the pounding when she is having these episodes. Your input would be appreciated on your thoughts about these symptoms and whether the combination of drugs may cause this.
