molluscum contagiosum

hi, I'm in need of some advice as my 5 year old son is suffering from molluscum. He has had molluscum on & off for the last 4 years or so. Since this summer it's getting progressively worse, it has spread so much, most of them are on his genitals, bottom, legs, arms, chest. I have been giving him thuja 6 for the last month morning and evening, can't see any dramatic improvement. Some of the lumps on his legs became quite big and redish, hard with flaky top and red/inflamed skin around them (i guess it has to do with clothes rubbing them). Am thinking to try thuja tincture as bathing solution for the lumps, also maybe i should give him echinacea q... Generally he is healthy, yearly this year we had 3 ear infections which we treated with homeopathic remedies, after constitutional berylium 1m we seam to managed to get out from the infections. Should i try it again?

Thank you!
