Hello, Many people talk about "Energy blocks". Many alternative therapies are based on it. We can think something about variations in blood flow as a mechanism of "blood flow controls/regulations" which may alter blood flow, cause cogestions, vasodilations and vasoconstrictions etc. There are also some other unstabilities as mucus congestion, acid base and water imbalances etc. As mostly thought, such energy blocks are related to neurological system. What can be the patho-physiolgy of these so considered as "energy blocks"? Can there be some unstabilities in neurological system in signal movements which can be interpreted as so called "energy blocks"? Best wishes.
