Had a traumatising experience with an Endoscopy 2 days ago..Immediately after the procedure (that I just about made it through) My face swelled, particularly under eyes, my skin was scarlet & prominent rash.
My throat also became swollen (I just had the Throat Spray, no Sedation) & I now have ulcerated toncills.
I've since found out this is a Petechiae rash on my face/neck/chest.
I spent all day yesterday back in hospital testing for an allergic reaction to the Throat Spray, however they lost my inflammatory bloods!! & don't seem to know what is going on with me? (My usual typical hospital experience)
Had further bloods taken again after 6hrs prior to the 'lost' bloods! & awaiting results?
I was wondering if these reactions are exaggerated due to my Behçets/ vascular response?
Or if these responses have happened to anyone else?
(I'm still traumatised by the whole experience & feeling very sorry for myself)
Bad experience at London C of E?
Neutrophil - low white blood cell count 
Depressed After Losing Peripheral Vision Loss
Colchicine side effects
Anyone taking Tramadol have bad night sweats?
Ugh, endoscopies can be brutal. Behcet's has so many overlapping features with other diseases it can be difficult. I can say that I have similar rashes on my arms and legs and no one has been able to figure it out over 3 three years. When I walk, the sores burst open in my legs and bleed all over. Did you have to come off any of your treatment for the endoscopy? For example my last Endo/colonoscopy was done on prednisone and now is rendered irrelevant so I need to do it all over again off of all meds that could hide a disease. Always take pictures of your symptoms, I have found that to be very key in my treatment. If you were indeed off your meds, you could be in a flare just from lack of meds and the stress of the procedure. I have to go to the hospital once a week for a direct bladder treatment via catheter and I always show up with a flare. It is something I need, but it is not fun in anyway! Just a few thoughts. Also, did they take biopsy? I rush to the derma office for biopsies, especially if in a new area.
Hi
thank you for your reply, I'm feeling a little less swollen & patetechi rash not as aggressive (Thankgoodness ) however I still have ulcers on my tonsills & now a few popped up on side of tongue (Behçets saying a hi no doubt :s ) Your leg rashes sound particularly painful! 
has the Behçets clinic had a look at those for you? It definitely sounds like an autoinflamatory response hey...
I did come off medication, I only take Colchicine (my bestie) & Vitamin D3.
I took my Colchicine dose later in the evening after the dreaded procedure this definitely helped I think prevent a full on flare. I'm still suffering with extreme stress from the Endoscopy, so I'm hoping my Colchicine is helping to dampen down any further flare as a result.
I don't envy you having to have so many invasive procedures , you sound incredibly brave
They didn't take a biopsy as the procedure was stopped before doing so due to my uncontrollable reactions.
I'm going to be further tested via Barium Swallow next week
They did manage to detect a sliding Hatial Hernia & Gastris (ulcer maybe causing? but they couldn't investigate further down)
I hope all goes well with bladder procedure & flare up stays as minimal as possible for you
Thank you for your incites & thoughts..
