So many. Mostly shooting pains in my legs. Especially after the first two injections. Hair loss jaw and ear pain. Swelling it seems after two month then quieting on the fifth month. Very gradually. The closer I get to the fourth and fifth month after the injection the better things got. Especially leg pain. Forgot to mention the lower back pain only lasted the first few weeks for me. But most importantly I wish I could spread the word that the last few injections have been better because a kind nurse told me to take an allergy medication like Zertec twice a day for a few days after the injection because she was told it helped. Well of course I tried it and although it did not take away all discomfort it did help! Is it real or imaginary I honestly don’t know. I will definitely continue. Last injection I took two a day for five days. Yet right now I’m on month four and having shooting pain behind my ear. It did this once before and settled down in a week.
