I believe its quite normal due to the hormonal changes. Best to rest and sleep, plenty or water and make sure to eat. Else, best to consult doctor.
Use a cold ice pack and lie on it for at least 15min the brain freeze will help with the pain
Try to drink more water.. And rest more.. Listen to relaxing music might help.
Might want to see a doctor. Don’t overdose on paracetamol
Did not occur to my wife. Maybe due to weather or stress?
Not so sure. It's sounds serious. Have u check with ur gynae?
