I have found the "before and after" comments very helpful. Thank you!
Here's my experience that I documented following my first Reclast IV in February.
I'm 72, 5'4" and in great health. Not an exercise freak, just very active.

Overall:
...Worst symptoms started 12 hours after infusion and lasted until early morning day three.
Aleve worked better than Tylenol.
Worst pain was left side neck, both arms had lack of range of motion. Chest tightness on day two.

Daily/Weekly:
Day 1: taking 1 Tylenol arthritis every 4 hours. No side effects until 4 AM. Severe bone pain and bloating. Brief chills.

Day 2: chest tightness and bloating, joint pain, still taking Tylenol. Brief chills.
Temp of 102.4. Took Aleve at 7:30pm.
9:15pm temp 101.5

Day 3: Aleve much better at relieving symptoms than Tylenol. Aleve at 7:30am. Temp 100.1 at 8am.

Day 4: Aleve 7am. Temp 99.3
Headache Tylenol 10pm temp 99.1

1 week: strong pain left hip. Aleve barely helped. Difficulty walking. Ice worked.

2 weeks: stomach issues bloating/ diarrhea. Seriously thinking about not doing this again. Feel feverish and nauseous. Fatigue is high today.

3 Weeks: Finally feeling better.

Because I know what lies ahead of me come February 2027, I will take the treatment again. I'm told the side effects are lessened on dose #2??
