hello, I have been experiencing a tingling prickly sensation when I touch stuff, for example my cell phone which is a touch screen, grip tightly a cup and even when I type on my computer keyboard. This sensation is only located on my finger tips. Towards the end of the day my hands (palms and fingertips feel relief when I hold something cool). This has been going on for about five days now. please do help!

Hello dear, The symptoms as mentioned in your post can be attributed to:1. Compression of nerve fibers at the upper limb, either due to mechanical compression or spasm of para spinal muscles.2. Inadequate HY Chat Doctor. 3. Dietary deficiencies of certain nutrients like Iron, Calcium, vitamin D, Vitamin B12, Folic acid, etc. which help in blood formation & nerve conduction.4. Peripheral neuropathy caused due to any fluctuation in blood pressure or blood sugar level. Symptomatic relief can be obtained by intake of cervicogenic agents (like Vitamin B6, Vitamin B12, Folic acid) as well as multivitamin & multimineral supplements including iron, calcium & vitamin D needs to be added in your diet. Physiotherapy & postural exercise will also be helpful. If symptoms still persist, kindly consult a Neurologist & get a complete Neurological examination done.
