Pain

I had the sleeve done last year in May. Where my drainage tube was (after they pulled it out) I have had pain in that area. Its like right where my ribs end on the left side. I am not pregnant and my pain is getting worse. When the pain started last year my doctor who did the surgery did almost every test you can think of to see why I am having this pain and it all came back clear, they don't know why I have it. But since my pregnancy its getting worse and I am not sure what to do anymore. I am asking if anyone has had this type of pain before and if so, tell me what they did to help you.
