Why would I have a pain in left testicle and a pain in lower abdomen? The pain in abdomen has been constant for several days and the pain in testicle comes and goes. Also I feel that I need to have a bowel movement and the sensation to urinate constantly?
Thanks for asking in Chat Doctor forum Your symptoms are suggestive of urinary tract infection leading to pain, frequency of urination.  And left testicular and abdominal pain may also be due to varicocele as it is very common on left side.  So, please visit a doctor for physical examination & further investigating the cause for your pain with urinalysis.  All the best.
