Okay I have been trying for a year to find answers to my symptoms, but the only thing my Doctor says is anxiety. It started almost a year ago with my heart feeling like it was going to beat right out of my back, and yes I had anxiety because I thought it was my heart but I went to the hospital had stress test and echo but found no problem just high BP and now have that under control. I think maybe my symptoms are associated with my IBS (I have had a clean colonoscopy) because I get a tingling sensation in my right foot, shin, forearm and sometimes dizziness right before and after a BM or with heavy gas, this seems to come in waves lasting about 30 seconds per wave for about 5-10 minutes. I tell my doctor about it and she smiles and says they never heard of this and it must be anxiety I still get the "thumping" every once in a while, and it usually seems to happen when I eat a heavier meal and feel full. I also get charlie horse cramps in my ribs, chest and back and just recently I have a vibration buzzing in my left foot that also seems to come in short waves that can last quite a while, it feels light and I really only notice it when I am still or trying to sleep. I had a MRI of the brain and it was clear so now the doc just keeps saying anxiety. Now I am no doctor but I do know myself and I don't think that these are anxiety attacks I have had some and can tell the difference. Please help me find at least a direction to look for possible answers. Thanks so much
