I am a 16 year old female and about 2 months ago I noticed this patch of blood in my armpit. It was about a centimeter in size, and looked like a patch of blood splattered under the skin. I didn't think much of it cause it went away soon. But now I have a little dot of blood under my skin on both of my knees.
I also have several hard bone-like lumps on the back of my skull near the bottom. They are completely painless and all about the size of small marbles. They feel attached to my head. Some of them started to get sore and grew about twice the original size. But after they got really big and sore, they shrunk. Now they're a little bit smaller than they ever were. But now the lymph nodes in my neck are swollen, some painless and some tender.
I noticed another one of the bone-like lumps near my tailbone. It's about ping pong ball sized, immovable, and painless. The lymph nodes in my groin are swollen(painless) now, too.
It is not possible to diagnose the type of cancer, and also if you actually have cancer, just by the description provided by you.
Lymph node enlargement is a very common sign and can cause many people to get stressed and lose their sleep. A few major symptoms and danger signs can help you differentiate very common benign conditions from those indicating conditions like cancer and chronic diseases.
Symptoms like persistent fever, weight loss, night sweats along with multiple enlarged, painless lymph nodes may indicate conditions like lymphoma or cancer.
Smaller single nodes, that are tender to pressure without any other signs mentioned above can signify many common conditions including including upper respiratory tract infections, chronic infections like tuberculosis, local asymptomatic skin infections, etc.
The recent onset of red painful bumps in the neck indicate lymph node enlargement associated with local infection. But if it has been persistent for a longer duration could be due to a chronic infection or a systemic disorder.
You might consult a doctor for a physical examination and proper advise. In case of doubt, he might advise you to undergo a biopsy of the lymph nodes for a definitive diagnosis.
In the mean time, you can take Advil or Motrin , for a few days, and apply cold packs over the lumps. This measure, will help in resolution of your symptoms to some extent.
