Hi,
Welcome to HCM,
After a long dental procedure, getting
cold sores and peeling of skin in surrounding area is a known after effects, specially in those people who have loose underlying tissue due to old age or some other causes. You may need to use some ointment containg
Zinc oxide. If ulcer between teeth is due to that procedure, and painful or infected, you may need to apply oral paste combination which contains Antibiotic and
Local Anaesthetic medication. You should also take
Folic Acid , which helps in mucosal healing. If you have done all above measure, and not getting well, you must see Medical practitioner.
I do not think that it is due to chronic effect of
Lyme Disease. For your bladder control, you must see a urosurgeon, who can rule out any prostatic cause for urinary symptoms. If cause cannot be detected, it could be due to general loss of muscle strength of
urethra due to old age. You need to do some exercises for
muscle tone. besides that, try to drink water in small quantity but frequently, and avoid drinking water 3-4 hours before sleep, avoid coffee, other beverages. I have tried to answer you depending on history given by you, but if you will see the Doctor personally, he or she may give you further specific advice. However you are welcome for any other query.
