Bed Allergy? Would love some advice
I'm a 34 year old male who over the past couple of months has developed what I believe is an allergic reaction to my bed. I started waking up a couple months ago with red welts/hives on my sides and hips. Depending on the day there could be 5-10 or my entire side. Up until this last week they could appear from my knees to my neck. I have been on a steady course of Zyrtec for the past 3 weeks. This kept the hives pretty much non-existent. This past week the hives were coming back despite being on Zyrtec. I noticed within about 10 minutes of getting into the bed a couple nights my lips would start getting welts. Last night it got to the point my face was covered with large welts. I have also had a couple times where I would have coughing fits in bed and would cough clear mucus for about 30 minutes and needed an inhaler to get some relief. Needless to say I need to figure out what is going on with me.
The mattress is a latex top and a polyurethane core. It's about 20 months old and have never had problems before this. I've been to the doctor and they ran a ton of tests. I passed every bloodwork test and there were quite a few. One included an IGE latex allergy test which came back negative. I have not been to an allergist yet because they are so booked (I go on 3/20). My wife sleeps in the same bed and has experienced no issues so it's not bed bugs. I don't ever experience these hives when sitting around the house in different chairs or on the floor. We have mainly hardwood floors and some area rugs. I've thought it could be dust mites, polyurethane or maybe latex (possible false negative test?) allergy.
I'm growing increasingly frustrated what I could be allergic to and just scared going to sleep at night. Sleeping in other areas of the house seems to help but would love to know if anyone has had a similar experience. Any ideas what's in this mattress that I'm allergic to? Thanks!
