Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. I think, this is due to obsession. You had that disturbing sensation once. You expected it to happen again and tried. Then you started experiencing it as you were expecting it. Then your body brought the familiar symptom because you are expecting it. Then you started worrying that the symptom is coming again and again and expect it. Body brings it again as you are expecting it. You become worried and so on. That is obsession in simple terms. Ignore it and the problem vanishes. Many researches and researchers confirm that medicines alone cannot cure mental disorders. Life style changes, change in thinking pattern, relaxation etc are as essential as medicines. Psychotherapy can help you changing your lifestyle and thinking patterns.
