### input:
Hello, I m a 25yo female, 5 4 110lbs. For about one year I ve been experiencing sporadic chest pains that quite literally paralyze me because I cannot breath and feel as if I m being stabbed in the chest. About 4 months ago, for no apparent reason (other than not eating all day), I fainted. I ve never fainted or came close to it before so I was slightly concerned but almost positive it was just low blood sugar. I ve been experiencing excess sweating just in my under arms for about a year as well as chronic cold hands and bruising. I ve had problems with excessive bruising since my teens and saw a hematologist when my general care physician found my PPT was high. The hematologist could not explain the bruising but said I was otherwise normal. The bruising continues today but are now on my arms. Last week I noticed that my first rib was elevated or swollen. It doesn t hurt but is clearly raised on the left side. Today I noticed my collar bone is now swollen. The swelling is in the same spot that the chest pains I referred to occur. I also notice a quarter sized lump on my lower back to the right of my spine. The lump is painless, hard and stationary. I m wondering if I should see a doctor. I recently moved to a different state, haven t found a GC and haven t paid my high deductible for the year. Im not sure considering the hurdles that seeing a doctor would be beneficial.

Hello, I passed carefully through your question and would explain that your symptoms could be related to the lump may be a lymph node or any other lesions. For this reason, I recommend consulting with your attending physician for a physical exam, and an ultrasound of the lump, in order to examine its nature better.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
