Hi. Thanks for your query. Noted the history and understood your concerns. Tingling sensation on the right upper side of abdomen, top of back and which increases or comes on only after putting any pressure on it like sitting or bending indicates that there may be a problems with the nerves, rind or spine of the upper back which supplies the sensory nerves to the affected area. I would advise you the following in such a situation: Get a clinical evaluation, examination and investigations as indicated to get proper diagnosis and management. Get an MRI of the whole spine done to know the exact cause. Tests of blood and urine helps occasionally. Get the treatment as per the findings so that a proper cure can be made. It may need a corrective surgery now or in future if there is prolapsed disc. Do not do any work or exercises that can cause straining on the area. Take bed rest.
