So I have arthritis in lower back, left hip bursitis, tendonitis in the left guteous medius and minimus, I am waiting for a CT . What could be causing my lower left abdominal and testicle pain when sitting
It could be the position your scrotum is in - the muscles could be putting pressure on an inflamed prostate. Switching positions alleviates that pressure. It might be a trapped nerve.
Pain with sitting is a common symptom of prostatitis.
