I tried fish oil supplements a few years ago for no particular reason other than it’s supposed to be beneficial and all.
After about a week of this I lightly bumped my forearm against a wooden post and I immediately had a brilliant port wine stain from wrist to elbow. It was very impressive. It also made me wonder if I could bleed to death after imbibing fish oil. Probably not, but I decided fish oil wasn’t for me all the same. Baby aspirin makes me bruise easily too, just not as dramatically as oil of salmon.
The photo of mitch shows a small taped down- what is called a “pick” line for insertion of a syringe tip (minus a needle in other words) for administration of medication liquid form. The location is a vein, venous pick line, on his right hand.
The right hand is discolored/bruised from a venous sub-cutaneous bleeding (injury? bump? or did he fall down bracing with right arm- he is right hand dominant?)
The other hand is also discolored but not as much, more red.
Venous bleeding— probably from anticoagulant. Tpa? could be, or something older— like coumadin/warfarin.
