Question: Hey......This problem started happening 2 weeks back. That day i had a bottle of beer in morning w/o breakfast......after a night of excessive drinking. then i have a heavy chicken based lunch outside and the weather was very hot. Prior to that i had been travelling for last 20 days in extreme weather. So the problem started with a throbbing type of pain in penis area and a burning sensation during urination. There were little redness inside the penis head(opening). I met a sexologist, practising near my home and he prescribed basic UTI based medicine, although my basic urine culture test came normal. after taking medicines for 5 days, pain got a bit better (half in intensity). I decided to consult a specialist urologist, who asked me to go again for urine test in addition to blood test and a sonography of lower abdomen. Though, my urine, blood and sonography examination came up normal, doc. decided after seeing the sonography film that problem might be due to prostate cysts. He prescribed me with Docycycline capsules (an antibiotic), Tab Gabapentin for 3 weeks and asked me to go for Sitz bath twice a day. Its been 5 days since i have been following the advice consciously. But the problem has aggravated a bit as other than preresiding throbbing/burning pain in penis/urine, lower abdomen pain has also started which is increasing day by day. I don't know where i am going wrong. I don't know if its is linked, but i had a unprotected intercourse around 4.5 months back.
Please help me, while you can. Thanks in advance.

1) No i didn't had any similar problem/complaint in the past.
2) Like initially the colour of urine was very dark and i always felt like i have to go to toilet. Atleast 8-10 times a day. But recently it has colour has become normal but a burning sensation while urination is still there. Frequency is right now around 6-8 times a day...maye be because i am drinking lots of water.
It is constant in nature but it is more felt/predominant during evening hours.

Also, i have started drinking canberry juice (somewhere i red its helpful in urinary infections). I am drinking lots of water.

Flow of medicines as per the attached prescription. All the reports such as urine culture, bloodtest, sonography are attached for reference.

Well i have been taking Doxy Cycline Capsules & Gabapentin tab (both 1OD) since 12-06-2015. Also, i have been taking setz baths with warm water twice (morning and evening). I have definitely observed improvement in the original problem/pain i was suffering in penis/urine. But exactly the day after i started these meds, abdomen pain started to set in. So, that's what has been my main worry. Today i had a followup session with my doctor and he has asked me to continue with the same two tabs. Also, he has prescribed Tab Drotin (SoS) in case abdomen pain becomes worse. But he seemed quite satisfied after again going thru my sonography film, that the problem would be resolved.

My question is : is it possible that this abdomen pain i am getting may be a side-effect of medicines i am taking. Because, i am not having any problems like acidity or constipation which may cause stomach pain.
