Earlier In Week I Was Getting Dizzy And Naucious After

earlier in week I was getting dizzy and naucious after eating. Actually after having a protein drink of protein powder, strawberries, half banana, chia seeds, flax seeds, hemp seeds, MTC Oil, apple cider vinegar. I have been drinking this for quite some time often in the morning...the only new changes were the MTC Oil and apple cider vinegar. I eliminated those thinking they were the issue. I had the normal drink but same issue...then I realilzed the protein powder had a date in the past (expiry date) so I think that was the issue. However, sometimes when I eat since then...I do get "a little" light headed still. Not sure if it is just my body not recovered from the original drinks (like a food poisoning) or not. My left shoulder and arm have bothered me over the last few weeks...but that is something I have experienced in the past...thinking its from lying on it. This morning my left arm was numb when I woke up - no feeling but I do lie on the arm alot. Should I be concerned.
