Always a tingling sensation in urethra.

Hi, 4 weeks ago I had a lot of friends visiting and there was much partying and drinking etc. After a couple of days I felt a sensation in my urinary tract and soon later pain spasms with headache started in my bladder/pubic region. I quickly took Norfloxicin 400 for a week after which it was bearable. I wasn't able to concentrate and it was intense. Then a family doctor suggested Ofloxocin and I had it for 8days and went to a urologist who changed it to Cipro. I am on complete rest with 0 physical stress and 10% mental stress due to work - not much. But now every time I feel a slightest bit of stress (physical or mentally) I get a tingling sensation down near the penis. Can some one help ? Is it a nerve problem or perninum disorder ? Or is there something I should do to control this from happening? Any help would be appreciated. I am scared and not a joyful person anymore with all of this effecting my personality.
