i recently had a blood test.
could this be connected to the fact that the end of my penis is swollen.?
i'm not in pain and can urinate easily.
could this be a circulation problem or something else?

Also,
i have had pains under my shoulder blade for 3 months.My doctor originally thought i had a muscle strain.
I have had a chest x-ray which came back normal.
Hence i have just had a blood test.
Could this be serious?
