Why is there blood when I blow my nose? Explanations please?

ENT check. The nasal mucosa is a very vascular structure and blowing too hard may rupture a small blood vessel. Such bleeding can usually be treated by taking a piece of cotton baton, put it in ice and insert into the nostril and squeeze for about 3 minutes. However, you really need a specialist to look at your nasal lining and septum and make absolutely sure you have nothing more serious. Read more...

Multiple causes. If you are still experiencing shortness of breath, it is advisable to seek medical care. Your physician may order a chest radiograph, pulmonary tests and a blood count.

The bleeding should stop quickly in this case. Read more...

No. Nose bleeds especially after blowing are very common, especially in winter months. As long as you are not pouring blood, don't worry. I would put a little neosporin inside your nose to lubricate it. Congrats btw! Read more...

I am having upper back pain that comes and go, and blood when I blow my nose. I do not have a cough. I am 25 and I don't smokecould I have lung cancer?

Almost certainly not. I don't think you have lung cancer at all. Back pain can be due to many things (including posture, very large breasts, etc) and blood when you blow your nose is probably due to a polyp. Obviously you should have it checked out if it's a lot. But at your age and with no smoking history, lung cancer would be very low on my list. As for bruising and weakness, you should probably have a blood test. Read more...
Unlikely. At your age, cancer unlikely if otherwise healthy. If you have weight loss, breathing issues, nausea or night fevers. You need to have pcp check it out. Read more...
