It's interesting - maybe many of us have high level of lymphocytes? But I still have no idea what is the source of this infection (probably infection).
I don't think that it's just a coincidence - my lymphocytes were fine 6 years ago and during the last 3-4 years they ALL came back high (I'm testing my blood once a year).
Here are the answers for your questions:
I feel tired all the time and my BO usually get worse when I'm not getting enough sleep.
I don't have any problem with my muscles at all.
I get constant cold especially during the winter.
I didn't have fever for the last 5 years - maybe even more.
