A constant sound much like the night air sounds of rural Florida woods with crickets, cicadas, frogs and such with their symphony of sound all night long. I have this sound full time and have been taking 2 to 3 Vicoprofen a day for three years. I am wondering if the Vicoprofen is the cause. It started about 7 months ago and only has gotten louder. I just stopped the drug two days ago and hope in time it will go away? Will it? Is it the cause? Anybody know anything about this?
