Today I felt some improvement in the morning.
At the radiology new X-rays showed that the seroma cavity got significantly smaller.
By the evening the swelling is much smaller and much more bearable than yesterday.
I did the Betadyne flush again tonight. Now I will wait and see if I will be set back with new reaction... May be it was Betadyne....
It might be that the corner is turned... Keep fingers crossed.
Morning update: Slept all night without pain/sleeping pills. There is definitely a progress.
