Yellow is lovely and shows that your little “micro” is resolving on it’s normal schedule. I know everyone wants a specific time and date but that is somewhat depending on the individual. There is absolutely nothing you can, or should, do to make this go away faster. I’d say, just forget about it.
My own horrid jaw infection resolved, the pain is gone and I sort of thought it would never go away. I too wanted to know “how long!” The body is truly amazing and nearly all of what’s going on (at the cellular level) we have no clue at all as to what’s happening.
I always like to ask clients the following question just to give them some pause as to the miracle of our body: Question: How many cells, in our body, are duplicating in ONE second? The answer is 10 million (per second). Sometimes we just have to let Mother Nature “do her thing” and not over-think our issues … because we will never understand all the processes going on.
In your case, your little amoeba-like macrophages are squiggling around and gobbling-up the dead red cells. Just “chill” and let the little monsters enjoy the feast! (Of course, if it’s Amber Heard, the bruises come and go at the convenient photo-op time.)
