Sheeks - I don't know about
the EO, but my husband did use DMSO on a tendon - right knee area.
He had bashed it at work...and it swelled up...pushing on the knee cap...lots of pain.
The orthopedic surgeon told him that all he could do is surgery which involved him shaving off part of it.
Husband said 'no thanks'...and used the DSMO on it..(he swears by it) and the swelling went down within a short time.
Never had an issue since...that was many years ago.
So using it on the tendon with EO may be even better. You try the antibiotic in it and let me know how it goes...maybe I will try it on my shoulder blade area... you first.
