I'm so sorry, Tbohl!! Warm salt water rinses (do not 'swish' with any force, very, very gentle) will help the skin heal.
I had dental implants placed last year and discovered (while in desperation) that the plant (weed) called plantain can really help a LOT with dental pain. All you do is bruise the leaf and place it on the site of the pain.

As Annette suggested, please increase your detoxing to help ease those symptoms. Things like soaking your feet in Epsom salt & peroxide, dry skin brushing, oil pulling (again, very, very gently!) will all help you to ease your symptoms.
Don't forget that this is traumatic to the body too! So be kind to it with lots of rest and good care.
I hope you feel better very, very soon!
