Thank you for asking your query at DoctorSpring.
Lack of response to Z- pacs does not necessarily mean a viral infection. Although as you suspect a viral infection is a possibility, a resistant bacterial infection, and even a non-infectious cause also should be considered. There are hundreds of common viruses (which can infect humans) and you need not test for all of them ! And that is not the right approach either.
From an STD stand point the ones tested are adequate. You may get tested for Hepatitis B (if you were not vaccinated previously). Instead of focusing on the virus the approach should be to find out what is wrong. I assume you have done the tests after adequate interval. ( at least 4-5 weeks after contact. Too early tests might not give correct results)
I recommend the following steps for the purpose.
- 1. A thorough Physical examination by your Doctor, including examination of genital area of candidiasis / lesions / warts.
- 2. A routine blood test – Complete Blood count, Fasting Blood sugar
- 3. Urine Routine Test
- 4. Liver and Renal Function test (To be decided after the Physical examination)
- 5. You can take a OTC pain medication like Ibuprofen 400mg twice daily for the back pain and legs.
There is no reason to be paranoid. A basic blood test will rule out the common issues.
Hope this helps.
