Hi,
Welcome to ehealthforum,
It is difficult to comment on the âballâ that you describe without examining you. You should consider visiting your gynecologist/obstetrician for examination when it is prominent. The possibility of you feeling the cervix, retroverted uterus, or a cyst or polyp cannot be ruled. Only after careful examination the cause can be made out. If any abnormality is detected, appropriate treatment options would be suggested (based on examination findings and investigation results).
Take care.
