Allergic reactions

After I gave birth to my daughter, my endometriosis was getting worse and worse so decided to try the Mirena coil again.
As soon November 2017 it was fitted I was in worse pain, by 8 weeks in I was bleeding so heavily that I felt weak. I was also having allergic reactions every 2 weeks and had to go on steroids to keep it at bay. By 3 and half months in I was bleeding still as heavy as when it was put in. enough I had it removed by GP thought that maybe my reactions were to progesterone. The reactions kept happening after I had coil removed. I ended up being referred to an Allergy specialist for testing. while waiting to see a specialist I had a reaction so bad that I ended up in resus as I could breathe.

When I got to the allergy specialist and I went with photos of my reactions and a diary or when they happen they said they thought I wasn't allergic to progesterone. I asked about the allergies to medications. she thought it was likely I wasn't allergic to them either but instead suffer from a form of urticaria.

They did skin prick and then injection tests of progesterone, all the antibiotics I have had in the past and all of them were negative.

A few months later I went back for further testing of progesterone I was giving 100mg and had to be monitored during my time there. Again no reaction. They said I have Chronic Spontaneous Urticaria. this means whenever my body is under physical or emotional stress my body produces too much Histermine and causes an allergic reaction response. 

I got put on a high dose of a mix of antihistamines and other drugs to stop my reactions. while I still have the reactions they are not as bad as some have been in the past. But these drugs also mean my immune is weakened and so when I catch a cold its worse than I used to be. My most recent cold went on for over 2 weeks and ended up turning into a sinus infection. I feel like life is a bit of a balance of all my conditions. Due to the urticaria my endo doctor doesn't want to give me treatments for my endo (menopause injections) as they could set off the urticaria and if that happens then they cant stop the reactions as they can't take the injections away.
