tested negative for hpv could I still have genital warts

I've been feeling off for 3 weeks. My neck is stiff I have chills a cough I had a rash on my eye brow and one behind my knee.  Red bumps and white they go away and come back. I've had a sore throat. I have hot and dry skin I have stomach pain sometimes off and on. I don't know what's going on with me. I've been back and forth to the doctors. They don't know. I'm worried.😭
