In the past 2 weeks I have had allergic reactions to some mystery thing. Reaction 1 was after eating cranberry. I turned puce and very hot and my heart raced. My ecg showed regular heart rate, though high. It passed and they told me to take anti histimine. I take one every day already. Yesterday after eating rye bread I turned red and hot, then mottled then white and faint. In between times i have experienced episodes of skin flushing and increased heart rate. These are different from the tamoxifen related flushes ive had for years. Went to doc yesterday who said it is likely that it is something interacting with my drug regime. I take sprycel and tamoxifen and supplements. I am fairly certain it isnt a food allergy. I had rye bread an hour ago and no reaction. No one seems concerned. My haematologist said it was highly unlikely to be a reaction to sprycel at this point. No one feels it is of concern which is great, but the episodes are frightening and unpleasant. Any similar experiences?
