You had NO RISK for HIV and DO NOT NEED TO TEST.
If you did NOT have unprotected oral sex, you NEVER had a risk for STD's
Your symptoms, as you stated yourself, were from the cold that was going around in your locality. The doctor diagnosed your swollen lymph node as being caused by throat congestion. Believe him. And believe me when I tell you that you do NOT have HIV.
One word of advice. NEVER hold information back from your doctor. If you're going to do that, why bother going at all.
No risk for HIV. Your symptoms are not related.
