I have never received a medical device card for my breast implants even after contacting my surgeon. What should I do now?

I am sorry you are having these issues.  If you are not able to obtain the information from your surgeon you can contact the facility where you had breast augmentation surgery.  You also can contact the manufacturer of your implants.  Regardless of the type of implants you can elect to have them removed at any time.  The specific implant information is not needed in order to remove them.

I am sorry to hear about your concerns after breast augmentation surgery. Contacting your plastic surgeon, the surgical facility, and/or the breast implant manufacturer should provide you with the information you are seeking. Regardless of the type of breast implant  involved, it sounds like you are heading towards breast implant removal and capsulectomy surgery.    Some general thoughts may be helpful to:You will find, that there is no consensus among plastic surgeons, whether or not there is a link between breast implants and the medical conditions of concern.   In other words, as of today, there is no scientific "causation" shown thus far.  The main theory currently involves a complex interaction of breast implant material with the patient's immune system,  Involvement of bacteria/fungal/virus/other adjuvants, as well as the patient's specific genetic makeup. It is theorized that the "wrong combination" of these parameters may lead to autoimmune disease and/or other associated systemic symptoms.   
However, personally  having worked with many patients who have presented with concerns regarding breast implant illness, I think (as thoughtful and humble) physicians, it is important to keep an open mind (even though there is no definitive scientific demonstration of breast implants and specific illnesses except for a very rare lymphoma) and remember (again) that we may very likely do not have a full understanding of breast implants and the potential interactions that may occur with each patient's unique biology.   It is clear, based on the literature and my own anecdotal experience, that a significant percentage of patients who undergo breast implant removal surgery (and capsulectomy)  do experience improvement in symptomatology. On the other hand, a similarly significant percentage of patients continue to experience symptoms despite breast implant removal/capsulectomy surgery. in my practice, I encourage patients to seek second or third opinions from relevant physicians ( for example, internists, rheumatologists, neurologists, depending on the patient's symptomatology profile), prior to proceeding with breast implant removal surgery.
 
  I hope this helps.
