Try to relaz abit as you do not have a risk for hiv because you used a condom.
Also all the symptoms you mentioned sound more like anxiety rather than ars symptoms,
forget about hiv and move on with your life.
If a condom fails it rips down the seam so that didn't happen. You can't get hiv when you use a condom, so your problem is not disease, it is fear of disease. "...because I am too paranoid.."
See doc, or a physio person for your back since this is an hiv prevention forum and stop examining your body cold turkey because a sore throat that was barely noticeable was likely in your imagination.
