Thank you for waiting. Your angel has symptoms of hole in the head disease, which is fairly common in angel fish. It's believed that several factors interact in causing the disease, but a parasite is the initiating cause. You'll need to treat with metronidazole. There are details at this site:
If you can't find any locally, here is a site that sells metronidazole:
A larger pet store or aquarium shop may keep this medication on hand, too.
It's also important to maintain water quality and feed an optimal diet. Anecdotal evidence from fish keepers suggests that it may also help to keep the gravel no deeper than 1/4 inch and to use a one of the BioWheel type filters.
As for the wound on the other side, the metronidazole may also help with that since it does kill some types of bacteria. If it is not looking any betetr after treatment, you can then run a course of an antibiotic, such as Melafix.
If you have more questions, just let me know. Thank you very much for bringing us your question.I hope your angelfish will recover.
