[SSSSSSS]

I feel a burning sensation under my armpit. I suppose it's because the cup is putting pressure on it, but I'm afraid I might be damaging a nerve. I don't know if it's just paranoia, but I've noticed a very subtle tingling sensation in my shoulder  (I'm very hypochondriac). And no matter how low or centered I place the cups, they always end up positioning themselves in a way that causes pain in my armpit. What do you think?

Stop pumping until the pain goes away, this can be serious. In order to move the cups away, try pumping with one cup only (alternate sides every 15 minutes), this way you can more easily center and move down. If it rides up, try something like wrapping a towel around above to keep it down. Also try padding.
