I would give one dose camphora x30, or 6c, and wait 24 houers to see, it can be that sulphur causes this, and it is either a prooving, or to low potence, or to high potence used, it depends wether the symptome are new and unrelated to the picture,( then a prooving), or if reocurrences of a old symptome, the potence is too low, go up a bit.(on sulphur). But it reminds more of a prooving, antidote.If still there two days after antidoting, use Tuberculinum.
As fore natrium, well natrium is better in evenings, nigth, worse morning.
