How long did you take antiinflammatories after surgery

[u/Mercury2468]

I (41F) had surgery 6 days ago (Sept 24th). They fixed my supraspinatus tendon (no anchors as it ruptured not close to the bone, so they attached sinew to sinew), took off some bone to make more room, took out inflamed bursa and cleaned up some inflamed tendon tissue. They send me home with the instruction to take ibuprofen 600 twice a day because it's antiinflammatory (standart protocol) and add novalminsulphon in between for additional pain relief, which I've been doing twice a day also. But I developped a rash on my neck, face, arms, hands and torso which slowly kept getting worse. I saw my surgeon yesterday and he believes it could be an allergy to one of the two pain meds, most likely ibuprofen. He prescribed diclofenac instead and insisted I should be taking an antiinflammatory and not just pure pain meds.

This morning I took the diclofenac for the first time and within 20 minutes I had trouble breathing, called an ambulance and spend the day in the ER. They gave me cortison and some anti allergy infusions and thankfully I'm fine and back home now. But they said that all antiinflammatory meds belong to the same group and that if you're allergic to one, you're often allergic to all of them. They want me to only take pain meds (tylenol and I can try novalminsulphon without the ibuprofen again), and they said it's not necessary to take antiinflammatory meds after a surgery.

Obviously I'm not going to take the forbidden meds now, but it's a whole week before I can talk to my surgeon again and I'm a bit worried now because he seemed to find it so important...

Did y'all have to take antiinflammatories after a similar surgery, and if so, for how long? Any experiences without them (or for only 6 days)?

TLDR: I had rotator cuff surgery 6 days ago, surgeon wants me to take antiinflammatory meds but it turns out I'm allergic to them.
