Can this be an encapsulated seroma? TT revision 3 months post op. (photos)

Had TT revision in April and now have this lump on the right side of my bb. I initially had a seroma form 3 days after surgery but my PS said it was very small and would absorb on it's own. Since I had my surgery in another country I have only communicated with my PS through email. I sent him pictures and he suggested I inject metilprednisolona will this help? I do have to admit that I have continued aspirations myself, now it's only about 10cc's that come out and it's a pink colored liquid. HELP!!
