HIV sympton

Hi Doctor,
I had 1 encounters with SexWorkers  in the month of Nov09 and 3 in second week of Dec that was the last one , but  I had protected sex all times.During that time I had a dental infection  ie my tooth filling had come out and there was a cavity in the tooth , the tooth was painful , I received oral sex , I kissed the ladies deeply , I suspect that becuse of my tooth infection I was infected with HIV from someone. Two weeks after my first encounter I had a sore throat  , then two weeks later I had constipation  , I decided to go for HIV testing  at week 5 after my last encounter on Jan 08 , the results came in two weeks after as Negative for all STD, but now I am feeling very weak in my legs , specially in my left calf , just like jelly legs , tired and I have developed a rash on my inner thighs , which comes and goes. My constipation hasn't yet gone , I have also developed a itch anus which sometimes have a discharge. At night there is a tingling feeling on both of my elbows.
My question to you is please could someone help me to tell that :
Is the Five week HIV test accurate
Why I am having this stomach / anus itch problems
Does the HIV rash comes and goes on the legs.
The night tingling feeling on both joints of elbow
Iam very worried , please help I shall be very gratefull to you
Thank you

explain "encounters".    

did you have unprotected vaginal and/or anal intercourse?

I Lizzie sorry I forgot to mention what encounters , they are sexual! I am sure I had fully protected only vaginal intercourse for just 5 minutes for each of the encounters, next 5 to 8 minutes was oral sex with a condom  and some time deep kissing .
Thanks for your help and interest.

You never had a risk of contracting HIV.

Hello Lizzie thanks for responding so quickly, I am living in fear  to ask questions why I am feeling so weak and lathargic , is the HIV test result in week 5 false negative!
