So it is advisable to do colour Doppler limb to see vascular status. medication physiotherapy with TENS and anodyne therapy may help. For these symptoms analgesic and neurotropic medication can be started. I will advise to check your vit B12 and vit D3 level. There is possibility of transient ischemic episode or stroke leading to motor weakness on arm and leg. You may need clinical examination to confirm neurological weakness, BP and other vital parameters. MRI brain will rule out stroke in case of suspicion. Hope this answers your query.
