All are true about intermittent claudication except
<p> Intermittent claudication: Crampy pain in the muscles seen in limbs. Due to aerial occlusion, metabolites like lactic acid and substance P accumulate in the muscle and cause pain. Site of pain depends on site of aerial occlusion. Most common site is calf muscles. Pain in foot is due to block in lower tibial and plantar vessels. Pain in calf is due to block in femoropopliteal segment. Pain in thigh is due to block in superficial femoral aery. Pain in buttock is due to block in common iliac aery. Pain commonly develops when muscles are exercising and relieved on rest. Beta blockers may aggravate claudication. {Reference: SRB&;s manual of surgery, 5th edition , page no. 170}
