I'm in need of a medical opinion. I have a character who contracts a disease from her (non-exclusive) partner while living homeless and taking a variety of street drugs. I'm looking for a disease she could have contracted under those circumstances which would steadily worsen over a period of ten to fifteen years, eventually resulting in a very messy death--as it's currently written, the character experiences hemmorhaging and convulsions, and then death. I'm wondering if this is at all realistic, or if I need to start looking for new symptoms. Any ideas? Thanks in advance ...
