I Have Been Diagnosed With Mold Exposure In Early February.

I have been diagnosed with mold exposure in early February. It is now the end of May. I was at that time taken out of the environment. It is now the end of May. Have seen some improvement, but my neck which was very stiff improved about 90%. However I still seem to have a slight stiffness in the neck that sounds like air bubbles at times when I move my neck. What is possibly going on.
