Best pain patches manufacturing company

I recently purchased some pain patches manufactured by Pharmaforce after my c-section as i was in alot of pain and these pain patches did the work,after i placed them around the painful area and left it for a bit and when i took off the patches i was actually pain-free and felt so much more better, i was even in shock and denial that there was really no pain and these patches drew all the pain and did an excellent job.
