@elissams143 and @linepa2002 Since CLL is very slow to develop. In all likelihood, it had been going on years before you received the Covid vaccination. Correlation is not causation.
However, Covid is an insidious virus, whose long term side effects are now causing myriad complications in lungs, heart, brain, joints, skin, bone marrow, etc., so while it’s possible your cases of CLL are related to this, there’s no way to be certain.
Unfortunately, aging, exposure to chemicals, radiation, pollution, contaminated foods, molds, etc.. also have the ability to cause similar inflammatory or cancerous issues. And sometimes, as my oncologist told me when I wondered how on earth I ended up with AML…”Sometimes S**t happens and you’ll drive yourself crazy trying to figure out the cause.” I trusted this man with my life so I’m going with that…there was no assignable cause.

If I can share with you my philosophy, I never worry about ‘what ifs’ because it’s a thief of time and causes anxiety. Each day is a gift so try not to worry about ‘what if this happens’. If/Then is a better choice. If something happens, then I will deal with it. Until then, focus on positive things. Eventually they will push out the negative thoughts. What brings you joy each day?
