I understand your concern, because unlike most people here you were actually exposed to HIV.
However, your 7 week negative test rules out that you have been infected, so get that out of your mind.
Besides, nobody has ever been known to get infected from such an exposure.
Bottom line: trust your doctor, HIV is not your problem.
I don't know how my friend 'regular joey' A.K.A Dr.Stupid concludes that you were exposed to HIV but the fact of the matter here is , your question has been answered by the best guys here (above) who really know their stuffs and they have told you that you never had a risk, so you should believe it rather than believing some one who knows nothing about HIV.
If you ask me, I'd say you are good to go, easy !
theoretically you have a risk of around .03 % or less, and testing at around 50 days ,especially if with symptoms most people would seroconvert, and you can breath now you are not infected... if it would help you calm down your nerves get tested at 3 months and i would expect tobe negative...
While I am not a physician, I will take a crack at answering some of these questions. You, of course, have already had advice from at least one physician, so I am not sure if this is going to help you in any meaningful way. But, with that said, here goes:
You asked: 1) If I was converting with those symptoms, especially the lip sores at days #33 and 34 would the test be positive by day 50? 2) What else can give lip sores that go away in 2 days without treatment?
Answer: I would imagine that yes, if indeed you were seroconverting, and these "sores" were a manifestation of your converting from a negative to a positive status, that yes, an antibody test would have shown positive by day 50. Seems logical to me that you would have indeed tested positive in the indicated time frame if you were presenting with ARS some 16 days previous. Perhaps someone a bit better qualified than I would like to answer this question, though.
As for sores in the mouth, nearly everyone gets these from time to time in life. Funny thing, I used to get them when I was a child, quite frequently, but they went away when I hit my teens. I went through a bit of an HIV scare myself some months ago, and, lo and behold, during this time I once again began to get ulcers in the mouth. Long story short, I eventually tested negative for HIV, and realize today that what I thought was a symptom of primary HIV infection was really a symptom of the anxiety and stress of worrying about HIV.
You asked: 4) Do my symptoms sound like seroconversion illness?
5) How would you quantify my risk?
Actually, not to me they don't, given what I have read about symptoms of primary HIV infection. The important point here, though, is that symptoms really do not mean much in terms of diagnosing HIV. I understand that it is only natural to worry, at times, and I also understand the tendency to attribute normal and minor changes in your body to HIV when one is in the grips of HIV anxiety.
Having said that, no, your "symptoms" do not sound much like symptoms of HIV infection.
Body temperature: just for the record, your body temperature will fluctuate during the day, sometimes dramatically. A 99.5 body temperature would not, I believe, qualify as a fever.
Swollen lymph nodes in the neck: It is extremely difficult to diagnose oneself with swollen lymph nodes. Thus, it is probably unwise to even try. You sound like you are in the medical profession, so you probably know what happens when you spend much time poking and prodding your lymph nodes: the notion that your lymph nodes are swollen becomes a self fulfilling prophecy. Besides, if the swollen lymph nodes were as a result of primary HIV infection, the swelling would be generalized, or, would exhibit in *all* of your lymph nodes, not just some (like, say, only in the neck, or only in the armpit).
Mouth sores: almost certainly a sign of the undue stress you are feeling right now. Stress, as you probably know, helps to debilitate the immune system to a certain degree, thus allowing the formation of ulcers in the mouth (caused by, most likely, a previous exposure to HSV - which nearly everyone *has* been exposed to at some point in their lives).
As for quantifying your risk, that has already been done for you by someone many times more qualified than I - the doctor(s) you have already consulted. You had a small paper cut, which had closed up. It does not seem to me that, even if the paper cut had opened back up to a small degree, that this healing cut would have provided a suitable route into the body for HIV to enter and establish itself. On the face of it, it seems like the chance that this may have happened is, for all practical purposes, zero.
Seems to me that you are unduly worried about this. Cannot say I blame you, but try to take a step back, take a deep breath, and put all of this into perspective. I know, easy for me to say, but given your description of the events in question, I believe you are going to be just fine.
If you feel that you can't shake this anxiety, sure, go ahead and test again at the 3 month mark. If your negative test then does not allay your concerns, it will be time to think about what to do next (such as, say, visiting a therapist who will help you come to grips with this).
In the meantime, I wish you well and good luck in dealing with your anxiety. Certainly, anxiety management should be your primary concern right now, not HIV, as it does not sound like you had any realistic chance to have contracted it.
Take care.
If I were you, I would:
1) Listen to your doctor. If he or she believes that you weren't at risk, then I would trust that.
2) Stop looking for and attepting to recreate symptoms. You will find them. This board is full of people that have every HIV symptom there is, including me. However, the VAST majority of all of us are negative.
3) Test again at 3 months if you can't let this go.
The bottom line is that you are HIGHLY unlikely to be HIV positive.
