A year ago I had a broken condom incident with a girl I met in a club in S. America. I had burning in the urethra for which doxycycline worked (treated after 3 weeks of symptoms). I was very very stressed about the incident and about 4 weeks after the incident my left foot felt a little strange when I walked as if I almost had a small lump on the sole (but did not of course). Over the course of 3-4 weeks my left foot started burning which then moved to my right foot and then my legs to the top of my thighs feel a sensitive sort of pain but only when wearing pants. My feet also only feel burning when wearing shoes and socks. If everything is uncovered I feel ok.
Basic blood work for tsh, sed rate, glucose, BUN, Creatinine, GFR, Sodium,Potassium,Chloride,CO2,Calcium,Prot ein,Albumin,Globulin,Bilirubin ,alkaline phosphatase, AST,ALT, Vit B12, and folate were all NORMAL. ALL STD's up to 6 months after the incident were also negative so I cannot think why I am getting these symptoms as I am an otherwise very healthy 34 year old.
What other tests can I get (if any) and do you have any ideas what this could be. I am not stressed right now (except about the symptoms) so find it a little hard to believe that stress can cause these symptoms.

Neurologist just said it was sensory neuropathy of unknown cause!!!!!

Any ideas?
