My 18 year old son was having chest pains earlier today. I took him to urgent care. His blood pressure was a little high and the EKG showed a slight arythmia. The dr. Wasn t too concerned, but suggested we follow up with primary care dr.Now, he is saying he s got numbness in all his fingertips, the very tips, but his chest isn t hurting. Should I take him to ER. He doesn t seem to be in distress, but it is worrisome, since they had asked him at urgent cAre if he had tingling in his fingertips, he didn t at the time, and his fingertips are really cold.
