I also have a horrible lymphoma fear. I've had night sweats going on 4 and a half months now :/ I have two pea sized furnish nodes in my groin, and I keep a close eye on my neck nodes and realized how much they change even due to a pimple on my neck. They are quite sensitive. I've had many tests in the last 7 months. 2 full cbcs and metabolic panels (most recent being this week.) ultrasounds, chest X-ray, 3 weeks ago a particular blood test looking for lymphoma markers . So far, even though I feel doomed, my tests say I'm okay and my doctor does too. Have you seem your doc and demanded the tests that will out your kind at ease? I just found out my friend who is 25 has had night sweats for the past 4 years!! They never found a cause and she still has them. It's apparently a tad more common than I thought in ladies our age. Not common where you hear people talking about it in passing convo, but it's not unheard of. As far as your weight loss, stress causes loss if appetite. As far as the jaw pain, I dare say your brain knows that's a symptom and it starts to act out on it. My subconscious has given me pains and symtoms of diseases I've heard if days or months prior! I remeber the first time it happened, I heard of a boy who got let cancer. A few days later out of the blue, severe leg pain! Oh no I thought! I must have leg cancer. Nope I didn't. The pain went away shortly . And this began my ongoing 10 year battle with HA.
