Hey
I'm not an expert or a professional but can share my own experinces hopefully providing you some additional insight to provide counter balance and rationale to your on going health concerns.. It's important to remeber they're many reasons and causes behind symptoms of which patient's who present with varied and non-specific symptoms excluding medical signs can find it very challenging in obtaining a diagnosis and you'll find many prevalent diseases are umbrella terms of disorders that fall under a broad category with multiple sclerosis being a condition of the central nervous system which the mssociety addresses the complex and challenging nature behind diagnosing reffering to non-specific symptoms which overlap with many other medical conditons..
It's further complicated by patient's who suffer with anxiety and/or depression as the patient experiences symptoms shared by many medical conditions.. It's easy to explain away symptoms but many illnesses are accompanied by anxiety and depression which can either be primary cause or secondary symptom but in brief many suspected illness requires thorough clinical assessment and medical evaluation to determine the causality of the symptoms
I find it helpful looking up extended definitions of medical terms across wikipedia, patient.info, nhs choices, and reading the full articles on

Might sound over the top and unnecessary but will provide real insight into the current state of affiars and following general pratice boards like pulsetoday and gponline etc. personally I'm trying to stop self diagnosisng and focus on improving my health through making dietary & lifestyle changes as I've wasted last two years and irrespective if I have life long debilitating disease I live with the symptoms and misery of it everyday so why fixate to slap a lable on it might as well just focus on recovery but I would recommend getting clinically evulated and medically assessed for burning/tingling as it suggestive of nerve damage which I suffer with lower right leg yet GP opts for low cost waitful watching and folic acid supplement as it shown to be "slightly" low =S ignorance is not bliss search everything then lecture anyone who undermines your medically unexplained non-specific symptoms and read my prior posts on challenges facing general pratice
