So I've had swollen lymph nodes in my groin (around 3-4 of them) for about 2 months now, and some swollen lymph nodes on my neck (definitely 4 of them) for a few weeks now. I also have pains in my armpits where the lymph nodes are. I have now also started to develop a sharp burning chest pain that never really goes away and can be most present even when I'm sitting doing nothing. The chest pain can either be sharp over my heart area, or aching to the point where I feel my entire chest is in agony. My muscles in my all my limbs but especially my arms constantly ache and feel weak as well. There is also these strange sharp pains I receive randomly in all over my abdomen, and some times even in my testicles. 
I've spoken to a doctor about these symptoms before and it was put down to a recent worm infection I had at the beginning of this year, however I have been worm free now for a while and these symptoms feel completely different to when I had the belly ache of having the worms. 
 

I'm really just wondering if anyone can give me some guidance to clear my head a little? I've been constantly so worried that I have lymphoma or some other type of cancer due to the constant feeling of being extremely un-well and run down and the swollen lymph nodes that have not gone away. My anxiety is through the roof with this. 
 

Cheers,

Azz.
