Thanks for the query.
It appears that the neck swelling could result from causes like an infection on the face or possibly respiratory infection. Other causes can also be there but one must think of commonest causes first. If the acne on the face are infected, it could be a cause for swollen neck glands as well. Even a sore throat
can cause this. Other causes like systemic infections and lymphoma need to be ruled out as well. Kindly consult your Internal Medicine Doctor to get a proper opinion after a detailed physical examination.
Fresh, red blood on the tissue could be a sign of hemorrhoids more than IBS. Kindly eat a diet rich in fresh fruits and green leafy vegetables. Drink 1-2 litres of water daily. Avoid constipation
. Get yourself examined by a Surgeon in this regard.
It also appears that you may be having a Vaginal infection
like thrush, yeast infection or Candidiasis
. This needs to be confirmed by your Gynecologist and after a few tests. Kindly avoid sex or masturbation
till you are diagnosed and treated completely.
Wishing good health.
