Thank you for asking your query at DoctorSpring.
I would like to know some additional information from you so that I can provide my best learned opinion. You can reply as a followup
1. Are having the tingling on the palms or back of the back side of had ? And is the tingling present all over the hand ? (Or limited to some part like the right half of palm, or over the thumb etc.)
2. Similarly which part of arm you are having the pain ?
3. "This morning I notice my left look to be swollen in one part and pressing.." Could you please make clear where exactly is the swelling ? Like on the front surface of elbow...or back of wrist....like that.
4. Is the cause for Anemia know ?
The symptoms appear to be of Neurological origin. So exact location of the pain will help me localize the lesion.
