Hi, please don't be so upset. A 1.6 cm cyst in the ovary is of no clinical value we don't even call it a cyst, it may just indicate an un-ruptured follicle which may be painful. Even then, if this is bothering you, all you have to do is repeat an ultrasound
pelvis after 6 weeks to make sure it has disappeared. All the other symptoms are likely to be related to your UTI. This infection may cause nausea, vomiting, lower abdominal pain
, back pain
etc. The antibiotic you are taking may also be responsible for all that nausea. Your dizziness
may be due to the medications you are taking for sinus problem. Your diarrhea
may be a consequence of antibiotic therapy or due to an ongoing infection. Just complete your antibiotic course and take any many medicine to stop your nausea after discussing with your physician. Please repeat urine culture some time after your treatment and period is over to make sure all has cleared up. May God help you.
