I have not had this problem nor had the flu in years. I eat healthy exercise take vitamins and get vaccinations which benefits my health. Those bad cells will attack a person’s body if given the chance? Protect yourself by doing things that benefit your health to stop future h although attacks?

I get cold sores, I feel it’s because my immune system is non existent. Speak to your pharmacist, I know that lysine is an over the counter drug . I also take valaciclovir 500 mg prescribed by my consultant, both help in the prevention of an attack of cold sores

I’ve had CLL for 11 yrs & have not had them. We’re all different tho. May or may not be related to CLL…many other things can cause a cold sore…

Yes, mouth sores and cold sores are a real concern with CLL. Because CLL weakens the immune system, the body has a harder time keeping certain viruses in check — including the herpes simplex virus, which causes cold sores. Mouth sores can show up for a couple of reasons:

- The disease itself — a weakened immune system makes it easier for viral infections to flare up, including cold sores and reactivated herpes viruses
- Treatments — certain chemotherapy and immunotherapy regimens can cause sores or lesions along the mouth and gums, which may bleed when irritated (like when brushing teeth)

It's worth keeping an eye out for symptoms like mouth sores, a sore throat, or toothache, as these can be signs of infection that may need prompt attention.

If new or worsening mouth sores appear, it's a good idea to loop in an oncologist. A dentist can also help examine areas of the mouth that are harder to see on your own.
