Pins and needles

2years ago I started to get a sharpe pain in my left shoulder blade it shot through in stages like sharp daggers,it moved around the shoulder area in different times of the day with no pattern,it then moved in under my rib cage area and adventually into my left breast. Which then only went into my ribs and breast after that. Could be 4 -3mins could go 4 a hour or two.could be 2-3days could be a week unpredictable with no pattern. After a year of it doing one day I got a strange feeling in my right arm my arm went numb then I got intence pins and needles in my hand it then spread slowly up my arm and then my hand went ice cold. I moved my arm around for ages it lastest 2ish hours of numbness with pins and needles and really bad poor circulation . Now after 2 years I get the pain in my ribcage and breast left side and pins and needles in my left hand and arm.... I'm worried and having problems with doctors to reconise what it is. I thought I had breast problems because of this should I see someone? I also have got numbness in my left side of face for about the same time but again at different times no pattern on and off lots and a little,manly a lot but I have had to learn to live with it ,it doesn't stop me from doing things but I'm always uncomfortable which means unhappy are they connected?
