I've been playing tennis for 15+ years & never experienced any hurt in my elbow. Since DEC last year I changed my Chang Precision Graphite LB to Head LM Instinct which strung with Tecnifibre Promix 17 String at 62 lbs ( i've never try this string before). After a couple of weeks hitting i starting feeling abit ( just a tiny bit) sore on my eblow but i still carry on play until when I playing my 1 round match in my club tournament against someone who serving very hard then my elbow pain became intensely during the match and forced me to withdraw. I have done things like RICE already including seeing a doctor and wearing a brace. During my recovery i have rest my arm as much as possible for nearly 3 months, now the initial pain is gone but I still couldn't swing my racquet without pain. I have check some posting here mostly say their injuries took them 6 to 8 weeks off from tennis then it went away but it didn't seem the same on me. it's been more 10 weeks but i still noticing my pain when i swing a racquet. I wonder how long it would take on you for a completely recovered ? Does my elbow hurt attribute of changing a new racquet with new stung?
