Yes they asked me to get her checked out , took ECG with me , went local GP as quite clued up as opposed to A& E where you don't know Adam . She was' nt sure about results on the Graph and my daughter today has a very low pulse rate ? And heart beat per min lower then average 7 yr old , she still is short of breath , but nothing that feels me with fear, as yet . An hour ago she said her neck hurts and to be fair there is a all swelling , not a lump as such just a mass of soft tissue below the top whet head joins neck but not near lymph gland ( know these well from when she had glandular fever) . Is it normal to ave so many symptoms and daily, hourly changes ? Dr said MRI scan week after next , do you normally have this or is it because of vision , headache , problems ?
