Sinus blockage symptoms and conditions

Dosage: 0.4mg / Day for 5 days.
Age: 26
Occupation: Chemist

Physical:
Feels like something is pulling down on my lungs inside of my chest. Sinus blockage. It feels actually like Viagra where there is swelling in the sinus cavity but not due to mucus. Result is a slightly blocked airway in nasal passage. NO EJACULATE, able to orgasm, but nothing comes out. (A good male birth control pill?) Sporadic, short headaches (~2-4 / Day). Shallow breathing, shortness of breath after going up stairs. Feeling weak all day long. Most of these probably due to lower blood pressure.

Mental:
Wanting to sleep more. A small lack of motivation to socialize, but not major. Annoyed / Angered more easily and often. (could be due to NO EJACULATE!!) A little humor there. No, seriously, I am really easy to agitate now. I wouldn't say lower sex drive, but more controlled sex drive. I felt horny most of the time before Flomax, but now only when engaged in sexual activity. (kind of nice actually) Haven't noticed anything about dream alterations.

Side Note:
The ejaculation part scares me a little bit just as others have expressed. As long as it comes back when I am off that is fine. Flomax DOES NOT shrink the prostate, it relaxes the prostate. I can see why this may cause a lack of ejaculate since the prostate in a way, a sperm valve. I feel like this should really be listed in the side effects but I know that masturbation is not part of clinical trials. Interesting though...could it be used as a male birth control pill? The first few days, a small small volume of ejaculate came out. Now, at day 5, dry as a bone.

Yea, ive taken this drug off and on for sinus infections for a couple of years. I wonder if this drug wasnt responsible in part for my sudden arythmia (untimely heart rhythm) and tachycardia (heartbeat over 100 bpm)... but on to the side effects ive gotten over the years. Basically ive noticed a feeling in my upper stomach like if i had almost acidic Gas or something, I get to feeling semi lightheaded and disoriented, Tired yet at the same time hyper which is odd.. like my mind is willing but my body isnt. Overall I feel malaise (feeling of slight illness)... think im dieing sometimes when on it! Heart Palpatations (when the heart is a little slow and then speeds up to catch up pumping a larger volume of blood through at once which is basically what it feels like... something hitting your heart from within). Anyway overall the drug is aweful... I took one today hoping it wouldnt hurt me too bad so i could get rid of my Ear Effusion(middle ear fluid), and my sinus blockage. I would suggest a reevaluation as well, I thought i was the only one getting all of these side effects for years until today. Go figure.
