Thinking about your dizzy spells, I noticed my issue was the blood thinner injections, blood pressure changes.
I would suspect that more than your allergies & claritin. Hope the dizzy spells have subsided so you can enjoy your driving again and swimming !
Can relate with the pollen...allergy stuff unfortunately - - got the respiratory stuff cough, some sneezing visiting again...seems to be the norm down here in FL (truly sub-tropical climate). Yep claritin, fluconase, darn....I love spring, but we are already in the throes of summer here 90's. Running a/c everywhere and shifting into going out in the eve, the hot sun and errands with a/c on max not my way of enjoying summer. (not a native here...from the midwest US - - full season of winter (don't miss) but having more of a spring and then summer

very enjoyable and not getting hit with the 90's and humidity until July into Aug. Well our trade off is short spring, long hot summer, I was told when I first moved to FL 12 yrs ago, no complaining about heat & humidity...consider that our winter, don't have snow nor frigid temps, but forced to survive staying in with a/c to tolerate the heat outside! so....which would you rather have

!!
Hoping you do well now getting into the full swing of things now...or even if it's little by little..this phase of your recovery, wc girl!! (lol! mine being sudden

stop sign & scare

post-op er/hospital iv antibiotics & out of state specialist trip)
