<s>[INST] My son-in-law fell out of bed (he s 30 yrs old) hit his leg, now has a nasty bruise with a blister ontop of it, the fall occurred Sunday night/monday morning since then the blister has gotten bigger and now when he sits for long periods and goes to get up there is pain and he limps for first several steps [/INST] dear madam,since he has a history of injury if i were your treating doctor i would examine the leg for any bony tenderness for ruling out bony injury andthen decide accordingly,if there is no bony injury giving rest to the part and analgesics, ice fomentation would suffice, and bruise it takes time to absorb. </s>
