Maybe someone can help me ....
1.About 7 months ago i went to the doctor with a swollen hard lymph node.... he felt and and was concerned and ran tests, all came back negative.
2. I started having night sweats but i was on anti depressants... so doctor thought they were related.
3. Lost about 40 pounds in the past 2 months... i started running and stopping taking my anti depressants about 2 months ago.
4. I do have anxiety ... that's why i run now, i dont want to depend on a medication to make me feel better.... even though it didn't work.
5. The past few weeks my temp has been Always 99 or above.
6. i started having night sweats again... im not on anything at all, this is when i started freaking out again.
7. I started getting little bruises on my calf muscle and arms ..... knees ext. they just show up... i do run but i dont know why or how i would get little bruises.
8. lymph node is still swollen... its like a little stone behind my ear... it doesn't move or do anything. i dont htink it has grown but i dont exactly know.
I am 19 years old.... on no medication and im not anemic... i just gave blood like a month ago and they checked.
...... any ideas??

See another doctor. You need to find out what is causing your symptoms.

you need a lymph node biopsy to rule out non-Hodgkin's/hodgkins lymphoma. You would also need to check out you bleeding factors which include checking your PT/PTT (because of the bruising)

you may wanna get tested for aids or hiv
