Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
The sore on your nose is in the "dangerous area of face" and that isthe reason there is so much pain everywhere. Regarding the painful lump near the occipital ridge, its probably a lymph
node as they are very commonly present there. Ones your nose infection settles down, the lymphnode swelling will also go down.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
