Flomax and avodart

I was taking flomax for a few weeks as I noticed a "strange" side effect. My sinus cavities were completely dry and open to the point of driving me nuts. This was getting me very depressed . I assumed every cause under the sun I did not realize it was the flomax until I visited my GP. He said to get off the flomax. Yesterday I felt good and thought the worst was over:however, I went back to taking cardura (with avodart) and I woke up this morning to the same symptom albeit somewhat less intense as the day progresses. Am I still suffering from the flomax or could it be the avodart?

Been on Flomax for 6 weeks. Seems to be of no value as far as frequent night time urination. Still get up multiple times. I have a feeling of malaise and zero libido and zero ejaculate. Also on Avodart for BPH and see no improvement. I think I will opt for either a laser or microwave treatment to reduce the prostate size at the bladder and get off these useless drugs.
