If somehow you suffered from Altitude Sickness, then it is necessary for you to stop trekking and take a time to acclimatize your body.
Porter-guides used to dealing with independent trekkers normally prefer to carry your backpack on their shoulders. They will likely carry a daypack for their own gear, packed on top of your pack or worn on their front.
Avoid climbs following heavy snowfalls especially on the Lhotse wall or the North wall. Climb swiftly past the dangerous parts, don’t climb the icefall too late in the day. Lastly, keep your fingers crossed and pray.
