Additional Information: Caller said she took her first one 18Mar2021 at the withheld and the second one 08Apr2021 at the withheld. She said after first one, her arm hurt for that day, and she couldn't lift it the next, then after that it was fine and dandy. She said after her second dose she was fine with no pain or anything. She said a month later the swelling started, and she didn't know or connect that to this until when she got her lung screening which she gets because she used to smoke up until ten years ago, which said problems were with lymph nodes. She said hers got hard. She said she had ultrasounds done and her mammogram done early, and a MRI done. AE treatment: Caller said that she used ice packs, which didn't work very well, she was about ready to lose her mind with ice. She said she tried heating pads. She said she took her pain meds that she usually doesn't take unless she absolutely has to, these were doing nothing for it. She said during this time the thing up under her arm was killing her, she was taking Hydrocodone 725mg, which she can take up to three times a day, but it wasn't touching the pain. She said she had that going on, so she took some of it, she only takes Hydrocodone 725mg when she was dying, clarified as dying in pain. Caller doesn't clarify this statement further. Caller said that the medication was in an orange pharmacy bottle, manufacturer unknown. She said she started taking Hydrocodone years ago when it was withheld, she doesn't take it on a normal basis, she only takes it when she was dying in pain. She said the medication is white. She said her call today has nothing do with Hydrocodone, she has a lot of medical issues, she was using it for up under her arm in particular at that time, it works normally for other pain, it didn't work for that. She said there was nothing wrong with it, it works, she already had some there, she was already using some on other problems. Concomitant Medications: Caller said she has a medication she takes for swelling, a water pill. No further details provided about her water pill. She said she takes Gabapentin, which she started taking over ten years ago for problems with nerve pain. She said she takes Naproxen for problems with muscle and bone pain, she has arthritis, so forth, so on, she was no longer a spring chicken. She said she started taking Hydrocodone years ago when it was Vicodin. Product strength and count size dispensed: 725mg, 90 tablets.   No follow-up attempts are possible.
