Hi, I have a lump in my left side, it gets worse after I have eaten, it is hard and growing, I have seen my GP and she does not seem to be worried, I also have cysts in both my kidneys and as such my Doctor has explored these with ultrasounds and advised me that if anything was there towards the lump it would show up, it is getting bigger almost like as large as a football, it is sometimes awkward when lying on my left side.  I have had a miscarriage and kidney operation on left side to remove a stone, and was advised several years ago it could be scar tissue.  What do you think, please help.  Joy Cash
You have said that you have undergone kidney operation for stone on left side but you didn't mentioned whether it's a surgery or a simple endoscopic procedure. Surgery usually leads to scar formation later may result in enlargement of scar tissue. Another thing which can happen after surgery of abdomen is development of hernia(since you mentioned the size increases after taking food). So whether the problem is scar tissue or hernia, in both the case you need to check wit a surgeon (general surgeon not GP).he will check you thoroughly and can provide treatment accordingly.
