Hi thanks for your question.
0ne important point in history you have not mentioned is your age.Having pain in lower abdomen with bladder full is normal and there is nothing to worry.Constipation
can also give rise lower abdominal pain
with full bladde as rectum or sigmoid colon
loaded with fecal matter can press on full bladder,which can give rise to pain.Adenitis can be a seperate issue and has no relation with pain of full bladder. Ciprofloxacin
is right drug for adenitis.
Hope this answers your question.
