Mouth Ulcers


Another question? I may have more but as I remember my symptoms, I really would like to know if anyone else suffers from these because of PA. Has anyone suffered from mouth ulcers due to PA? I am not sure if it’s the PA or something else but I constantly get them (at least once a month). After I started b12 injections, most of my symptoms went away except for the mouth ulcers and hair growth hasn’t started yet😬

I get these when I need an injection, it was one of the first symptoms before diagnosis


Hi runnergirl24. Yes, I get them too...and once I have a crop it takes them a good while to heal. Ouch.

Both B12 deficiency and iron deficiency can cause them, along with other systemic illnesses (particularly inflammatory ones - IBS, Coeliac and Crohn's disease and other autoimmune conditions).

Good idea to get ferritin levels checked, if you can (one marker of iron deficeincy Anaemia) to check and see if you have iron deficiency anaemia too (those with absorption problems often get other vitamin and mineral deficiencies). And iron deficiency can also cause hair loss or problems with hair growth😖.

Here's some more information about mouth ulcers:

When they're really bad I use Boots Mouth Ulcer Gel 15g (contains Cetylpyridinium Chloride 0.02% w/w, Lidocaine 0.6% w/w) - the local anaesthetic really helps with the pain and the Cetylpyridinium is supposed to help with healing (but no idea about that - just happy to have the pain relief).

So...unfortunately, you're not alone in the mouth ulcer department 😉😀.

Thanks for the info.

I use Peroxyl mouthwash and it really helps :)

I get them, too, and my mother, who also had PA, used to get sores under her dentures (ouch) when it was near time for her next injection. A mild salt and warm water rinse can help discomfort. According to my Neuro nurse practitioner sometimes a weak vinegar and water rinse used regularly can keep them to a minimum. I haven't tried this yet, but I think she said something like a teaspoon of vinegar to 2 cups of water. ( No doubt Dr. Google will have the exact measurements somewhere.)

Thanks for the info. They can be quite nasty at times. My dentist asked what I do for them. I told him I just take the pain😀
