Have little bumps on palm and finger. What could this be?

Bladder issues: leaking pee and a burning sensation during peeing. Dear reader, I am a 17 year old girl experiencing some bladder issues lately. My problems started about 1 1/2 month ago: I noticed I had to go to the toilet a lot, and I also noticed a burning sensation during peeing. I had to change panties quite often as I would find that they got really wet (not because i was aroused, I think it was sticky discharge combined with pee, because it was yellow colored). Also, when I have sex, I constantly have the feeling i have to pee (but that might also be because of the position). Around the time these symptoms occurred I also felt a slightly painful and uncomfortable feeling during sex. I thought I had a bladder infection, but when I tested for that the results came back negative. THen I went to the doctor, who couldn t think of anything else besides a possible yeast infection or STD. I got tested for both, but yet again the results came back negative. The symptoms went away for about a month, however the past few days I noticed that I ve started leaking again. It has come to the point where I have to change panties at least 3 times a day. I noticed that the fluid is very clear and that it is pee. I also feel a burning sensation during peeing and sometimes even when I am just sitting I can just feel some pee leaking out of me. Some extra useful information: -I have been sexually active for some less than 2 years now, have had the same partner all along, never contracted an STD. -Me and my boyfriend have sex without a condom, however I am using birth control pills (have been using then since the start of me becoming sexually active, so almost 2 years now) -Have had a yeast infection a few months ago, had it treated by putting a ball of cream (forgot the name of the thing) inside my vagina for three nights. -I have had a lot of problems with bleeding during intercourse. It started around the 5th time I had sex, and lasted for about 1.5 years. (However, there was a period during the summer of 2011 that I didn t bleed for 2 or 3 months). For the past few months I have not bled, which might have been a result of me changing my birth control pills. -The doctor performed a pap smear on me in April 2011, because of the problems I had with bleeding during sex. the result: I have pap-2 and do have the HPV virus. I am scheduled to undergo another pap smear in November, to see if it has gotten worse or better. -I do perform kegel exercises on a regular basis, and have been doing so even before I started to become sexually active. I do not think that my muscles are the problem. -I did a pregnancy test last month. The result was that I am not pregnant. Thank you for taking the time to try and help me with my problems, I really appreciate it. Also, I would like to note that I live in the Netherlands and English is not my mother tongue. I apologize for any mistakes or unclear explanations, I have tied to state everything as clearly as I could, however I found it a bit difficult. best regards, Roxanne
