Symptoms you may not connect

Itching. Brain fog. Rage. Migraine. Relationship doubt.

Some are recognised PMDD symptoms. Others may be premenstrual, cycle-linked or signs of a separate condition. Explore the difference and choose what to track.

Important:Itching is not a core PMDD symptom and should not automatically be described as a histamine reaction from PMDD. A repeating premenstrual pattern may still be useful because skin conditions and rare hormone hypersensitivity can be cyclical.
Read the label before the list

Not every cycle-linked symptom means the same thing.

Evidence labels keep the page broad enough to recognise real experiences while preventing the assumption that every symptom is PMDD.

Recognised PMDD criterion

Included in recognised PMDD diagnostic criteria, either as a specific symptom or within the physical-symptom criterion group.

Common premenstrual symptom

Commonly described with PMS or PMDD, but not enough on its own to identify PMDD.

Possible cycle-linked symptom

Some people report a repeating cycle pattern, but this is not a defining PMDD symptom and may have another cause.

Possible overlapping condition

May represent premenstrual worsening of another condition rather than PMDD itself. Medical assessment may be important.

Explore by body, mind or experience

Symptoms can look unrelated until timing reveals the pattern.

Select an area, search in your own words, or filter by evidence level. A repeating pattern is useful information; it is not proof that every symptom is caused by PMDD.

The pattern matters more than a one-off list

Record what happens, when it starts and when it lifts.

Daily tracking across multiple cycles can help distinguish a repeating premenstrual pattern from symptoms that remain present throughout the month.
