Hello I understand your concern. What you describe is called a parasthesia, an odd sensation when a particular area of your body is touched. There are multiple causes of paresthesias, including nuerological, vitamin deficiencies and even psychological. If you have seen many physicians already, I assume you had blood tests to check thyroid, B12 level, calcium level, magnesium level, iron level, as well as kidney and liver fuctions. Some liver and kidney conditions could cause parasthesias. Also some autoimmune diseases cause similar symptoms such as lupus or polymyalgia rheumatica. Next is to get electromyelograms with nerve conducting velocities of your arms or legs. This will help identify any problem with your nerves or muscles. Some types of neuropathies cause parastheias. Do you have any medical conditions or are you on any medications that could cause these symptoms? The causes as you can see are varied. You can also see a pain management specialist who can help with the parasthesisas. I hope you feel better
