Feels better for a day or two after chiropractor, massage, or acupuncture. No long term improvements.
Felt better for a couple days after anti-inflammatory injections.
Sometimes feels worse after massage.
Occasionally discomfort switches sides after chiropractor adjustment or massage, and I feel it on the right side instead of the left side.
Sometimes feels better with medications such as muscle relaxant or anti-inflammatory such as aspirin or ibuprofen. Muscle relaxant effect wanes after certain number of uses.
Stretches and posture correction aggravates it and has no long-term effects.
Thank you in advance for any help you might be able to give.
