Hello and welcome to HCM,
Left over tampons can be dangerous and can cause discomfort, infections and even
toxic shock syndrome.
If you are still feeling discomfort in the vagina, any left over tampon should be looked for.
There could be infection in the vaginal tract.
Is there any history of discharge from vagina?
If yes, then this could be indicative of vaginal tract infection.
Lower back is seen in association with
reproductive tract infection so this could be related to the
vaginal infection.
Sore throat needs to be treated with an antibiotic course.
If other family members are also suffering from sore throat or
respiratory tract infection, they also need to be treated.
Consult your primary healthcare provider for clinical assessment and management.
Thanks and take care
Dr Shailja Puri
