Are there things I can do myself to treat ear drum rupture?

Time Heals. Most ear drum rupures will heal on their own. The ones that do not , may need a surgical repair. Your doctor or an ENT should follow this. Do not put any ear drops in, unless prescribed.
Best to be seen. An eardrum rupture is usually a pinpoint perforation to let the infection out and most heal on their own with no problem. With a perforation though it is best to be seen...You may need antibiotic drops. The usual things i recommend for ear infections like garlic and willow oil cannot be used with a perforation. Chinese medicine can help and so can your doc.
