I saw my hand surgeon this morning for a re-evaluation of my tennis elbow after 6 weeks (12 sessions) of physical therapy. My Doctor measured my grip strength and said my strength had not dramatically improved. My Doc said it can take 6 to 9 months to fully heal. He gave me the options of allowing more time to heal by itself, or have a cortisone injection. He recommended the cortisone shot since my grip strength did not improve a lot. My physical therapist suggested 2 weeks (4 sessions total) of additional physical therapy and my doctor agreed to this. I will see my doc in one month to see if the cortisone shot worked. I will keep you updated.
