I recently saw a vascular surgeon re an abnormally low blood pressure and many times the clinician canot find it at all. This has been going on for about 10 years. After some testing the doctor said I have an occlusion under my rib cage on both sides and have had this for a long time. He did not recommend any treatment because I did not seem to complain about any symptoms (which surprised him)but I have trouble going up and down stairs and using my arms for any length of time ( thought this was because I do not strength train). I am 61 years old and am wondering if I had some type of surgery (not sure what that would entail) but would it help me in going up and down stairs and using my arms. If I was to have surgery what type is it? and how serious. I am very concerned and would like to be able to walk upstairs w/o my legs aching. Any advice or explanation as to what this is? Thank you
