I have a painless , closed sore on the tip of my penis from 3 years . I got few swolen lymph nodes 2 years back on my neck and it slowly went away . I feel pain in my legs since 2-3 years and it becomes very severe sometimes. But it mostly stays for 1 hour in the morning after waking up and then it becomes very less . It is becoming unbearable for me now and I feel depressed. I did syphilis , chlymadia and herpes tests and they were negative . What should I do ??
