Touching the back of my calf up towards the knee joint feels like really bad sunburn...yeah I'm not entirely convinced this is just parking near a nerve :/
Had something similar about 5 years back with high BA (as far as I know).. Severe pain in limb, redness, extreme headache.. It took 5-6 days to subside, could hardly walk, unable to touch site... grin n bear it..!!
Has anything changed, was it a new vial, or have you used previous with no negative effect..??
