Hello and welcome to HCM.
Thank you for your query.
Symptoms of a swollen and irritated vagina, along with a thick discharge could just be a phase seen during the menstrual cycle, when the vagina is at times thick and sticky, and sometimes produces a more watery discharge.
But, as this is the first time you have noticed this, your age would have greatly helped in further evaluation. If you are a middle-aged woman, approaching 40 years of age or have already passed it, this could be signs of an approaching
menopause, which results in reduced lubrication.
From your symptoms, it does not appear to be any kind of infection, but purely a
hormonal problem, either related to your menstrual cycle or a change in hormonal levels attributed to an approaching menopause. Both these conditions are normal, if present, you can visit your doctor and get examined to seek a solution and also to rule out any other possible conditions, as an online consultation cannot help in complete evaluation of any condition.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you.
Best wishes.
