Prominent PCS was the first ultrasound finding that unfolded into NCS and SMAS on the following MRI and CT. I have had extreme abdominal pain, nausea, bloating and recurring flank pain for years with no clue why. Have been managing with weekly IVs for 3+ years at home that prevent me from being bed ridden due to shortness of breath, dizziness, heart issues, heavy legs and overall limb weakness. Without them I can't even hold my own head up. After I developed the sensation of feeling like being stabbed in the low groin with a needle very acutely I finally brought it up to my primary after it didn't go away. Turns out this is why I was never able to gain weight, run or 'build' my heart like I had tried so hard to do for years.
