 One y.ago my fingers of left hand are numbed, am though, that a reason,am taking hard bags, but on this week is worsened, on nighttime very hurt, left-hand hurt, shoulder, breast. Feared, checked pressure, but pressure is OK, on the left hand is not ability check pressure just 70/60 shows, on right is stable on 115/70.

Advise me,  What is that?

These complaints having in many diseases as a very serious or not. And doctor here needing, and a most often same symptoms causing a so calling staircase  muscle syndrome is scalenus syndrome, where are vessels squeezed, feeding a hand with blood, and nerves are managing her work.

 Vital importance magistrates organism are vessels and nerves, are passing in canals of closed from  external affecting by muscles, fascias and bones, such bone-muscle tunnel having in low neck side, between clavicles and top rib. Canal is narrow hole, limiting from outside a front staircase  muscle and so calling between -staircase  space , and in result of inborn peculiarities , as of injuries, inflammations, tumors are other reasons are walls of canal are closing , squeezing a transferring in his structures: under clavicle arteria ,which carries and own blood from the heart to hand, and nerve plexus. 

And in peoples after 40-50 y.old a often  reason for staircase  muscles is neck osteochondrosis, he is developing within many years, with periodically aches and discomfort, as in occiput, neck, crunch in head mobility, headaches, dizziness.As having in close from neck vertebras a staircase  muscle getting anxious signs from a spine brain nerves and tensing, that leading to narrowing for between staircase  space.And  later staircase  muscle hardening, a part of her replacing a connective tissue ,that is more squeezing artery and nerves, going to hand. And its all creating background for developing  scaleus syndrome, and additional factors are: Inborn peculiarities for skeleton, additional neck rib, prolonging transverse processes of vertebras, protrusions, or hernias for intervertebral discs, injuries, obesity, posture wrong, long carrying hard bags in a hand or on the shoulders, constant loading on the muscles of shoulder waist, as in plastered ,painters, loaders, and other workers,  setting for muscle mass at fitness centre.

And after 4-50 u.old a not rare displaying scalenus syndrome provoking are chronic diseases for inside organs, and its tie with subtitle innervation.All body is covered with neck of nerve fibers, which forms a  one system, and disease displayed on the distance is reflecting on the neck muscles. For example, in gall bladder diseases a syndrome for staircase  muscle is developing from right, and in heart pathology is from the left in compliance for ache organ having.

 Syndrome for staircase  muscle enjoying displaying effectivity, as frightening for an all by own symptoms , as in adults are confusing with infarctus, or stenocardia, especially disease if acuting displaying, but a most often  process developing slowly, by increasing.

First symptoms for syndrome are hands numbness, as especially for  wrists'  fingers is small finger and non name , And in numbness are having tingling, goosebumps  crawling. After aches adding, as in neck, clavicle and lowering on hand, till fingers ending Sometimes she is spreading on the breast region, milk gland, spine, shoulder blades. Thus these symptoms in left side localization affecting on swallowing by patients nitroglycerine and calling for doctor with complaints on the heart.

But in compare from heart pathology, complaints in scalenus syndrome depending from head position and hand. Ache increasing in heart turning, incline in healthy side, moving ache hand back, up, and not tied with a common physical load, and a most often symptoms having on the nighttime or morning times. And on the acuting on damaging hand is arterial pressure lowering and pulse disappear, that a tie with over squeezed under clavicle artery. Skin of fingers and wrists are pale or blue shadow, later muscles  of hand atrophy, and suffering small fingers elevations and big finger ,that is leading to debugging palm relief and additional wrinkles on skin. Long destroying blood circulation and innervation of hand leading to developing a weakness of muscles ,if a needing working with raised hands up.
