Any Legal Recourse For A Tsa Experience?

I had a horrendous and very embarrassing experience at TSA. I am just curious if filing my complaint will even do anything or if there will be any recourse? If not, what legal action could i potentially take and where should I begin? I am happy to provide more information in the comments but here is my detailed complaint:

I wear knee brace to support my torn right ACL and medial meniscus. Before entering the body scanner I immediately disclosed to the TSA officers that I was wearing a knee brace. The officers pulled me from security for additional screening because of the brace, which was understandable and has happened before when I have travelled.

The officers asked that I sit down and pull up my pants up to expose my brace which I did to the best of my ability, but before receiving any additional pat downs, metal detector sweeps, or swabs I was told I needed to be moved to private screening.

I was forced to remove my pants multiple times while being observed by 4 male officers so my brace could be examined, then I was forcefully patted down without consent on my knee causing pain and discomfort. When I told the officer I was in pain and felt uncomfortable, I was told this was policy and that amount of force was required. Additionally, I mentioned to the officers that I fly often and this had never happened to me before at the security checkpoints especially at airports I have frequented this year including DCA, LAX, MSP, ORD, TPA, MDW, ATL, PHX, and DEN. They said that the other TSA agents at these airports have been disregarding policy and are in the wrong and that the private screening they were performing was all according to policy and was also being used for training purposes. If this was training purposes this was performed against my consent and without proper disclosure.

I was ultimately cleared though security taking 40 minutes of my time, I never once received an apology for how I was treated and as such I have cause to believe racial profiling was also at play.
