Allergies
This past week I had my annual physical during that appointment I had a tetanus booster (Tdap). Unfortunately I had a nasty allergic reaction so I've had a few lazy days recovering.
I experienced shortness of breath and my left armpit swelled up so bad, my left hand was numb/tingly.I'm slowly improving with 12 hourly antihistamines and anti-inflammatories every 6 hours.
