Syphilis & Hiv Coinfection

Hi,

recently I was poked with syringe when I was picking up my can from the soda machine.

I've had these symptoms:
1. Muscle n joint pains
2. Light lymph node swallon on neck n groin
3. Rash in week 4
4. Light fever which lasted for around 2 hours togather with muscle pain on my arm. This was during week 2.


After that, it has been confirmed at week 5 blood test that i've been infected with syphilis where my vdrl test shows reactive 1:16 titre. How ever, my hiv test shows -ve.

I was given penicillin jab twice and tablets to be taken twice daily by a skin specialist. How ever somehow i'm still getting some rash on my arms and thigh. On and off I get muscle and joint pain along with tinglish feelings. According to the doctor after my second jab the germs should be all gone or been killed. I'm not wondering if the treatment failed as i've had coinfection of hiv.

Can someone advice me on this. Please
