I have been expereiencing sharp shooting pains in my scalp sometimes occuring alone and other times occuring at the same time as a lower back pain on one side .The same type of scalp pains also occur when pressure is put on the lower left hand side of my back .What could be causing these to occur at the same time .What is most likely causing this to occur ?I have been to two doctors that tell me they do not know what is wrong with me .
