OK We can certainly continue after this but none of this is HIV related.
First off, contracting HIV through oral sex is extremely rare
Secondly, if one did contract HIV there would be not symptoms if at all for at least four to six weeks.
The numbness may be Bell's palsy--a problem with the facial nerve but not virus related
The small lump isn't likely a lymph node and more likely a benign sebaceous cyst
The diarrhea could be a benign stomach virus--not HIV or any STD problem
All that said, with any episode of unprotected sex like you had, you should undergo screening for HIV, herpes, and hepatitis in about three months after the potential exposure
Let me know if you need any more information about this please
