Hello,
Such type of burning sensation can be due to injury, infection (Epididymitis or Orchitis) or inflammation, testicular torsion -- most common in young men between 10 and 20 years old, excessive bicycle riding, hernia or kidney or ureteric stones.
The final diagnosis can only be made after a thorough physical examination including examination of the abdomen, scrotum, testicles and rectum.
Lab investigations like complete blood examination, urine examination, ultrasound lower abdomen and sometimes a urethral swab will help in diagnosis. Treatment will be started thereafter.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks a lot for the reply
I had tested blood & urine and also did ultra sound test of testicles. other than excess uric acid nothing came off. Testicles are perfect without any issues.
I ride motorcycle everyday for about 15 km (total 30 min) and the place i am staying is having a temp of more than 30c. also my job is to sit infront of computer for 8-10 hours daily. i do moderate exercise everyday , it started 1 day when i went for running in morning. is this because of motorcycle riding?
Thanks in advance
