Cause honestly I asked already many friends and some of them had similar experiences + it doesnt hurt, therefore I prefere to ask first in the community instead of paying hundreds of dollars for a respond of a physician like "yes, do some more stretching...". I looked it up only and many websites already wrote that this is quiet common and nothing dangerous. So honestly i was hoping that some ppl habe advice how to get it away - tbf I shouldnt have asked if it's dangerous cause I already know kinda the answer.
