Your question has been fully answered in this and your other threads about what is and is not a risk. This was not a risk for HIV. We are closing this discussion.

Firstly, it's practically not possible to get infected in that fashion. I would have been bit concerned if there was a huge gapping wound that happened right now to expose vulnerable cells inside of the body, it was profusely bleeding and it came in contact with the infected body fluid.
Secondly, the moment infected fluid establishes contact with the external environment, it degrades viral DNA as well as the lipids that make up the virus' shell, rendering it incapable of attaching to and infecting other cells.
You don't have a risk, there was no scope of transmission. No testing necessary.
As stated to you already, your symptoms are irrelevant to HIV.
Two months is plenty of time for a wound like that to heal. The fact that there was a scab there proves that it had already been in the healing stage. Added to that, HIV is only able to infect inside the body, so the only way this scenario could be a risk is if you didn't use a condom and had unprotected penetrative sex with her, which you did not. Being exposed to any body fluids outside the body is not a risk. The joint pain and stiffness is totally irrelevant.
