Hi,
How are you? Aside from the headache and leg swelling, what other symptoms are present? If you are referring to Athena Diagnostics which offers a series of blood tests, this help with diagnosing different kinds of conditions such as neuromuscular, endocrine, nephrology. It also tests genetic illnesses, which make it a bit more expensive than usual. Talk to your doctor about the tests that you are about to take to clarify any doubts. If Topamax is not working also, inform your doctor for proper management. A change of medication or dosage may be done. Take care and do keep us posted.
Have u looked the answer up on the web or looked in the doctors medical dictionary? Try there first. Dont know y everything cost so much> Perhaps Greed!
