Pelvic groin pain. Please advise.

I had spotted a bulge of about one inch around groin in lower abdomen 2 years back.. I had food infection that time and was treated with antibiotics. I found the bulge vanished after a week or two. Ultrasound came as normal since 2 years.. US spotted cystitis once and likely complex ovarian cyst once. Last 2 times completely normal. But since 2 years I am getting pelvic pain and left lower abdomen pain in groin area on and off .. especially when my bladder is full or when my tummy is full or during urine infection it gets worse and before periods it gets worse. Gynaec has suggested to ignore that .. but I can feel the pain anytime when pressed hard. I am afraid of going for any more specialist as they suggest expensive tests which might be irrelevant and every scan and blood test including RFT, Urine test , TFT, etc came back normal but usually Urine test shows Albumin high with no other traces. Please advise.
