Cipro is a reasonable antibiotic for prostatitis.
Lymph nodes around the jaw can be indicative of an infection in the head, neck or chest, as well as some STDs.
Observing the lymph nodes, so they decrease in size after the antibiotics, should be done. I would also be examined to ensure there isn't any other infection going on.
A urethral swab or urine sample should be done to check for STDs (like gonorrhea or chlamydia).
If the lymph nodes do not improve while on antibiotics, you should follow up for a more comprehensive evaluation.
Followup with your personal physician is essential.
