Search party symptoms and conditions

I have been taking flomax for a long time, i have had 5 operations due to my colon, when i became able to walk again i would loose by breathe just walking to the mail box in front of my house, and have ringing in my ears, i have been checked by a hart doctor and a pulmonary doctor as well, i am 100% in those areas, no one could find out why i had shortness of breathe, then i ran out of flomax. 4mg 1 daily, then my breathing rapidly unproved till i had no problem. no one ever thought to look at the possibility that it was due to the flomax until now.....
