Teak is correct.
1. There are hundreds of lymphnodes in your groin. Most are wheat-sized when not swollen. The ones in your neck are larger. A swollem node is easy to feel, you do not have to ravage your body looking for it.
2. It is too late for the typical symptoms of HIV. ARS sets in within 2-3 weeks and lasts 3-weeks maximum.
3. Do not speculate; just get tested. If in Canada, you can do an INSTI test and have results in 60 seconds, Hong Kong AWARE Oral and have results in 20 minutes, US OraSure in 20 minutes.
No they are not symptoms. You can test now and it will be conclusive.
