Hi Kathy
If by dr you mean your GP, please ask if you can be referred to a breast clinic. If it is the breast clinic you are going to, they usually do a triple test, e.g. mammogram, ultra sound scan and if they think it necessary, a biopsy. Just because you can't feel a lump, you are anxious about the heavy, swollen feeling and if only for your own peace of mind, it needs to be looked into.
Hoping for a good outcome for you and wishing you good luck.
