Pain in hands/arms: This sounds very much like a connective tissue problem. Best to see a rheumatologist for further evaluation and work up. Also with the tingling, EMG/NCS (nerve) testing also indicated. Your provider will know what this means and what to do. Best of luck

Pain all over: You might have Fibromyalgia which is a group of chronic pain disorders that affect connective tissues, including the muscles, ligaments , and tendons. The nerve is over active and causes this pain, cause is unknown. There are multiple medications to treat it. please see your doctor to r/o psoriatic arthritis.
