During this past few weeks, the same kind of things happen to me.
I always feel pain, something like "stitch" but not exactly like it.
I don't know how to explain it, just that when i walk, even slow walking, the "stitch" kind of pain will come. Is not like i'm walking on long distance. Is just a few metres, the pain will come. This happenned even when i didn't eat anything. When that pain starts, I will feel breathless. I can't feel that i'm breathing to my lungs.
and i become more and more forgetful. And i will feel sudden of giddiness.
