Swollen lymph nodes in neck, major swelling & welts within 24 hours

I thought I did very thorough research and went someone that had consistently good results. I had great skin before I just wanted to address some mild jowl laxity. I also spent extra for PRP directly after the treatment. Within 24 hours I had swollen lymph nodes in my neck, major swelling, welts and it just looked like I had hives over my face and neck. I was told to use OTC bacitracin and I was sent 2.5% hydrocortisone ointment. Does anyone have suggestions for the scarring and hyperpigmentation? I am just going to get surgery in the future when I need tightening, I’ve done CO2 lasers, sculptra, fillers, threads and have had complications with everything. I guess unless you’re a celebrity or influencer people don’t care about giving you the best care. I’m so upset.

Little to no improvement. Think I may be scarred for life. Have been in point with aftercare. The clinic has contacted InMode and they said it’s a “hypersensitivity reaction” I don’t agree with that because the only areas I’m having issues with are the areas the technician used intense settings and I think she was too aggressive.

It took 8 months for the hyperpigmentation to resolve 85%. Med spa owner was and is great he helped me with free products and TriLuma cream. The aesthetician that did this to me ghosted me though which I thought was unprofessional. I also started doing my own skin micro needling with exosomes at home.
