Tasmin had her first allergic reaction as a toddler. She later experienced issues with tolerating certain foods such as beef, tomatoes and fruits. She also developed more symptoms such as non-contagious conjunctivitis, asthma, seasonal allergies, eczema and reactions to certain laundry washing powders.
Tasmin was diagnosed with MCAS in 2020.
I felt very lonely and isolated while experiencing symptoms as things rapidly declined overnight, however I’m glad I persisted and trusted my instinct – although it was difficult as I was losing weight rapidly and unable to eat fully or drink water.
Mast Cell Action has been great for me over the past in answering any questions I’ve had about seeking help, or finding professionals in my area. I can’t thank the charity enough for being so supportive. Sharing experiences with a support group has helped me to manage my condition a lot.
