(Please be aware that I am not a pelvic floor health professional. I am simply sharing information that I have been studying and researching. It may be useful for some people but there is no one size fits all approach - everyone is different. It is recommended to get advice from a pelvic floor physiotherapist who can support you)
Having a tight pelvic floor doesn't mean that the muscles are strong. It means that they are overworked or holding tension. If you have a tight pelvic floor it is important to relax the muscles before trying to strengthen them.
Symptoms of a tight/overworked pelvic floor are:
Tailbone pain, painful bowel movements, constipation, haemorrhoids, difficulty urinating
3 ways to try and relax the muscles are:
Diaphragmatic breathing
Gentle pelvic girdle stretches
Stress reduction
