I have a cadaver acl, plastic miniscus & torn mcl. I recently aggravated my knee and have fluid & tight hamstring. Any home txs? No insurance

No! Get back to see your original surgeon, as the reconstruction sounds very complicated & unusual. You need a surgeon familiar with your case.
Ice, nsaids. Iyou obviously had a major knee procedure im not sure how it was paid if you have no insurance anyway i would recommend ice and NSAID meds i would hold off on exercises for awhile to let the swelling calm down you may need a cortsione injection.
