I have had a swollen lymph in my right armpit for 7 months now, it's not painful until you touch it then it's really sore. I have headaches, fatigued a lot, back ache at the top on my right side and a cough. I've had two ultrasounds which have come back clear and just said I have excessive tissue. I've also had a chest X-ray which I'm waiting on the results. As you can imagine Google is saying cancer cancer cancer but nothing seems to be showing up. Has anyone else had this problem and it either ended up cancer or not?

I also have been feeling unwell but not to the point where I'd be sick.
