28 year old male from england. One night in the middle of january I suddenly woke up in what I can only describe as a state of panic. My heart was racing I was heavy breathing and my body went really stiff, this lasted for no more than 5-10 seconds it has only happened once but since then I have had a pain in the left hand side of my stomach it feels like a knot like something is in there that shouldn't be, pain in my back the lower and upper parts the pain in my back started on my left side but is now on both sides. I've noticed 2 squishy lumps at the bottom left and side of my back. I notice the discomfort in my stomach more when i'm sat down as to when stood up or laying down. I notice when I urinate a lot of urine comes out but no pain or burning sensation or no more frequent than normal. I have suffered with diarrhea for many years now sometimes I have to use the toilet right after eating. But some days I feel constipated. I can see undigested food sometimes in my stool. I'm sleeping well and haven't noticed any weight loss. I sometimes feel sick but haven't been sick since this started. I have had blood tests done and they have all come back normal. I also did a urine sample and that came back normal. I am currently waiting for an ultrasound scan on the 26th of april. I had the lumps looked at on my back by 2 different doctors and they both said they didn't think they were of any concern. I have recently become a father for the first time, my son is 6 months old and he is my absolute world. I have suffered with anxiety for many years and I am now back on 50 mg of sertraline daily, because of my anxiety I have convinced myself that I have kidney or stomach cancer I spent a lot of time googling my symptoms. I spend most of my time worrying and crying that my son is going to grow up without me. My family history that I know of is diabetes runs on the female side (grandmother, mum, sister) my sister and father both have ibs. In 2019 my mum had stage 2 uterus cancer but has recovered well after surgery. My grandfather died of a stomach aneurysm in 2001 he also had stomach cancer at the time of his death. I've tried to be as detailed as possible with this and any help would be really appreciated i'm just so scared I don't want to leave my son.
