I went to a massage parlor and the woman sat naked on my back. Then I turned over for a handjob.  4 weeks later I noticed a small red spot on my skin.lower back, , It was flush with the skin., a week or so later I had another flat red spot show up and then a week later a brownish lesion flat with skin like 1/2 inch,, looked like a burn. It was not painful. I noticed these after I would cut grass for hours on the lawnmower. The original first red mark went away after a week,, maybe 8-9 days.. I picked at the other bigger lesion (spot on skin) and it came off and left a scar.
 

 I was worried it was syphilis. I went to my doctor and he said it did not look like syphilis. He knew I have anxiety so he did a RPR blood test. It was non reactive,. This was done 7 weeks after my massage experience. I was still worried and anxious after the test, so I went to my moms house and let her see the spot on my lower back. She touched it, Now I am worried if it happened to be syphilis could she have been infected on her finger? She is 83 years old.She ended up with a sore on her side of the thumb by the knuckle.  Then she had what seemed to be a bad sinus infection. Fever, very sore throat. 1 year later she has developed a pain in her right knee  and tenderness by the joint. I cannot keep it out of my mind for over a year now that what I had might have been syphilis and when my mom looked at it  she touched it ,that is might have caused a transmission,  not sure that part of her finger would have touched the spot I had but it still worry's me.  Please help

My main concern is that if it were syphilis and my mom touched it she might have got infected on her thumb. She got a sore on the side of her thumb.. then couple months later she got sore throat and tender lymph nodes . it has been a couple years now.. she is 83..  she has developed some memory issues and urinary incontinence..   I guess I am thinking that this is neurosyhilis.  she also gets lightheaded and her vision has changed som
