Hi welcome to HCMForum. It appears to be fissure in ano
or infected internal piles.
Other possibilities are sciatica lumbar spondylosis
or renal colic
. But none of them
will have oozing of blood. So i advise you to consult asurgeon or orthopedic surgeon
for diagnosis and treatment. MRI PROCTOSCOPY along with other routine tests.
Besides i advise you some diet recomendations as avoid taking potato other tubers
tomato cauli flower coconut till you get relieved of pain. I hope my reply is satisfa-
-tory to you. wishing for a quick recovery.
