ammonia wouldnt be causing those symptoms, you'd maybe get a rash or burn on your hand that would be gone within a couple weeks at most, it wouldnt explain things like weightloss and and muscle twitches 3 months after exposure.
You may want to consult a medical toxicologist.
Try this link for information on ammonia exposure, and agencies to contact for information. The first is from one of the most useful medical websites I've found:

Thank you. Could one of you you refer me to someone specific? I am getting worse and geting desperate. I do not think it is metal, rather it was ammonia. Sorry to sound so desperate.
With your symptoms I would think a Immunologist is the right kind of doctor to see . University of Chicago has a good record of doctors , also Northwestern . Or look into a allergy and Immunology doctor . I hope this helps . I have had a serious mystery disease and it took 8 doctors and 4 years to get to the point I am almost diagnosed . It has similar symptoms to yours . I finally had a second bone marrow sample sent to the University Of Michigan , Immunology department and am traveling there soon to have one more done to finish my diagnoses . I feel for you , It's just the worst to be sick and not know , knowledge is power , I hope you find help for yourself soon , Take care , Wendy .
Toxic exposure to heavy metals will often show up in a hair analysis. They can pinpoint almost the date of occurence. Do you know what the chemical was? Did it burn your skin or cause a rash?
