<s>[INST] Hi, I have had so many neurological symptoms on and off over the last 10 years it really annoys me if something else happens.  I have now noticed pins and needles/numbness in my left hand.  It has got worse in the last few weeks and is now there several times a day.  I have carpel tunnel and have had it for years, and that is in both hands in the first two fingers and thumb but I only get that at night or first thing in the morning.  This is different - it is during the day and affects my whole hand whilst I am using it, especially when my hand is not down.  Is it worth going to the doctor again? [/INST] Hello dear, The symptoms as mentioned in your post can be due to nerve compression secondary to Carpal tunnel syn Chat Doctor. Other reasons for such symptoms can be:1. Peripheral neuropathy2. Anemia (either Iron deficiency or It B12 deficiency anemia)3. Any abnormality in blood pressure & blood sugar levels4. Deficiency of certain nutrients like Iron, vitamin B 12, Calcium, etc. which also interferes with blood formation & nerve conductionSymptomatic relief can be obtained with intake of cervicogenic agents like It B12, B6 & Folic acid. However, the underlying cause needs to be treated. So, kindly visit a Neurologist & get a proper clinical examination done including nerve conduction studies. Investigations like complete blood count, estimation of blood pressure and blood sugar levels & Thyroid profile will be helpful. Wishing you a good health. Take care. </s>
