Slight tingling in my hands both especially through palms, weakiness, sleepiness, slightly short of breath, minor headache on the right side over right eye. It all happened since yesterday after I used Simple green cleaner with bare hands, I also feel heart palpitations for a few seconds and then it stops but tingling still is there. I am 49 and weigh 249 and lost 16 pounds in a month doing trademill. Target is 215. I have had history of acid reflux . non smoker, don t drink. no sore throat, no asthma . I also had colon endoscopy and it is all ok. These last two days I had rectal bleedind due to chronical hemoroides. tnx!
