Really chapped lips and sores around mouth?

[Guest guest]

Hi my 4 yr old son just completed his first round of chelation with

DMSA the 4 hour method. (We were doing the every other day per DAN but

he got fevers on 2 occasions with no other symptoms so I attributed it

to the chelation method) Anyway - he is not new to DMSA and even the 4

hour method he was only getting 200mg (2 capsules)in 24hours. Would

this constant chelation cause his lips to be chapped and he has 2 spots

around his mouth that look like white heads. His lips are so chapped

that even with chap stick applied a lot - they are bleeding. He did

have a cold about 2 weeks ago - maybe cold sores from that? But the

one whitehead looking thing is a good inch up from his lip under his

nose. Any ideas?? Thank you so much - Amber
