I have a question and I am hoping that perhaps someone here could
help me.

I was treating my rosacea last year with Doxycycline. I used this
medication for about two months and then stopped when I had a visible
allergic reaction to it. I had a spotty rash under both of my knees,
and I also had red patchy blotches on my face and back, which
appeared similar to hives and would itch on and off. I also had the
strong sensation of being sun burned on my arms and back, but I was
not sun burned. I had not been in the sun, at all, since this was not
recommended while taking this medication.

After stopping my allergic symptoms began to clear, but every now and
then I would still get a stray red patch on my arms or back, but it
would fade quickly enough.

However, I have now noticed that when I attempt to treat my acne
rosacea, be it with a doctor prescribed treatment, or be it with a
natural remedy, if my condition begins to improve at all these
allergic symptoms return. I don't get the rash under my knees, but
the hives, itching, and burning all return. Which I cannot
understand, as I have not used doxycycline for a year now, and the
other treatments I am pursuing are different than doxycycline, and
certainly I cannot be allergic in exactly the same manner to every
different form of treatment I try.

Could this still somehow be related to the doxycycline? That seems
like a stretch, but I'm grasping for an answer. I don't think that
this is due to any normal allergy, as it only occurs when my acne
rosacea begins to improve from a treatment I am trying. I know that I
am still experiencing stomach upset from this medicine, a year on- so
could it be possible that I am still experiencing other reactions as
well? Any help at all would be appreciated. Thanks.
