Sounds like you have a lot of multiple problems that are causing a lot of discomfort and anxiety. One more thing to consider as a contributor to your discomfort and anxiety is the psoas muscle. Look it up on an anatomy image. I am a massage therapist. I often deal with people that have anxiety problems. The psoas muscle is sometimes referred to as the iliopsoas muscle because the psoas and iliacus muscles of the hip are related in structure and function. The psoas muscle is known as the muscle of the soul because It is a large muscle that seems to react to stress. This causes disfunction and shortening of the muscle. Today’s world involves more setting behind a desk on the computer which also may contribute to its shortening. The psoas is in a shortened state when seating. After a lot of seating, it acquires this shortened state. The psoas attaches to the front side of the spine–starting at the T12 vertebrae ( around mid back area) to the L3 vertebrae and travels in front of the hip and finally attaches at the lesser trochanter of the femur. At the T1 vertebrae area the diaphragm ligament structure attaches to the top of the psoas. The shorten psoas cause the diaphragm to not fully expand and slightly effect your breathing process. If you suffer from the continual effects of a shortened poses it may cause discomfort and stimulate the “fight or flight mechanism” and thus the pain and anxiety. Hopefully, this may not be your case, but wanted to mention it as an additional contributor to your problems. Consider getting massages to help manage your stress.
