I did not know her health status , I had a hard rub penis on her vagina. But without penetration and trying to insert the penis, I may have entered a little but I could not Because I was not fully erect, I had a lot of anxiety On March 10 I had a normal test in the clinic, written anti hiv. The result was negative. After 50 days and 70 days I had the same test at the same clinic. The result was negative. after 10 weeks I had some symptoms of pain in the joints of the feet and hand and then disappeared after a week, ,on 19 May I done a test after 14 weeks in Laboratory tests  and the result was ,( ac anti hiv 1/2 ) (0.58 negative).Now I feel the same symptoms a week ago . I apologize perhaps my english is bad

This answers all of your HIV questions, and if you can think of any more just reread about the 3. You had zero risk therefore  testing is irrelevant to your situation because you had zero risk. HIV is a fragile virus, which is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.  
Only 3 adult risks are the following:
1. unprotected penetrating vaginal with a penis
2. unprotected penetrating anal sex with a penis
3. sharing needles that you inject with.
The only way to get HIV is if you did one of the 3. The situation you describe is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. This HIV science is 40 years old and very well established, so no detail that you can add to your encounter will change it from zero risk. Because of all the research statistics, doctors have calculated the risk from what you describe to be less than that of being hit by a meteor, therefore no one will get HIV from what you did in the next 40 years of your life either.
If you didn't have one of the 3 then you are just worrying about your own hiv theory - which is unrealistic for you to think that can become reality - so you should move on back to your happy life instead.
Since you had no penetration, the answers to your questions are:
1 Doesn't matter.
2 Doesn't matter.
3 Doesn't matter.
4 Also, your symptoms don't matter.  Since you don't have hiv, it is not surprising that the pain went away - I am doubting you even had any pain but it doesn't matter now.

It is not bright to try to penetrate a sex worker without a condom so consider yourself lucky that it didn't happen, and don't try it again.
