You sound like you’re do amazing.
Tightness is a thing and most annoying. I’m 9 m out now and wake up very tight, especially if I walked a lot the day before. Siting too long makes it very hard to get up.
Stretching, upright bicycle and I do use ibuprofen and sometimes extra strength Tylenol.
135 is amazing. I truly did not know the numbers or even to ask about how far before my surgery.
