Hi, I'm 36 and I've been having odd symptoms for around 18 months. It started with a pain under my left ribs which I'm pretty sure is my spleen. The Dr just told me I pulled something and sent me on my way. Then it progressed and I Now have acid reflux again the Dr instead of finding out why me a healthy weight, non drinking, non smoking, non caffeine drinking or spicy food eating person is getting acid just gave me omeprasole and sent me away.  This has also coinsided with awful hip and back pain with no explanation and the Dr deciding I have fibromyalgia. 

Now in the last 2 weeks almost all of my lymph nodes have swollen in my neck, I can feel a lump under my other rib and around my groin. I've not been Ill or had a temperature. I also just feel like crap, like all the time, for the last 2 years. 
 

i googled my symptoms (I know, I know) and the top hit is leukaemia. I'm worried my Dr won't take me seriously at all but I'm so tired of feeling utterly dreadful and being ignored. I tried another Dr at the surgery but honestly I get the feeling they think I'm a nut case. 
 

what can I do? How do i get the Dr to listen to my concerns?
