Is anyone having unexplained illness from splenda(sucralose)?

I have used Splenda for years, increasing useage in everything! Seems I have also developed strange unexplained medical issues, swelling, (now carry an epipen) mouth ulcers that never heal, painful bumps on tongue. Funny, I even crave real sweets more too!
The joke was seeing aunt julie with her large container of splenda that went with her everywhere! Now I am afraid it has made me sick?
