    Whether the pain in your hands is caused by trigger points, a muscle injury, or arthritis, compression has been shown to help with pain relief. The Imak Compression Arthritis Gloves are some of the best on the market.

    The gloves provide gentle compression, which helps decrease both pain relief and inflammation. The seams of the gloves are sewn to the outside so you will not have irritation or discomfort. The fingers opening is reinforced so that they will not fray with wear or during washing.

    To determine your size, measure straight across the widest part of your palm. Extra small: up to 2 3/4 inches wide. Small: up to 3 1/8 inches across. Medium: up to 3 1/2 inches across. Large: up to 4 inches across. Extra-large: up to 4 1/2 inches across.

    Pronator Teres Muscle Trigger Point Treatment

    The Trigger Point Therapy Workbook can help you treat wrist and thumb pain by teaching you the techniques to find and eliminate trigger points. Author Clair Davies explains the trigger point phenomenon and muscle pain in everyday language. But what makes this book worth its weight in gold are the individual muscle trigger point treatments that Davies has compiled. His diagrams and step-by-step instructions help you locate which muscles are contributing to your pain, how to find the trigger point, and treat it.

    If you are going to use the workbook, you will need a massage ball to do the treatment. Kieba Massage Lacrosse Balls can be used on muscles throughout the body.

    Another option is to find a massage therapist, physical therapist, or chiropractor with trigger point therapy training to show you how to find and treat the specific TrPs.

    Trigger points respond best to several 1-2 minutes treatments spread throughout the day.

An excellent choice for pain caused by trigger points, muscle/joint over-use and stiffness, and arthritis. You should keep Somba on hand; it provides almost instant relief for muscle and joint pain.

    Biofreeze Pain Relieving Gel is an excellent pain-relieving gel recommend for those who have sudden onset muscle pain or recent injuries.  It is better to use than warm therapy gels and creams for muscle pain caused by inflammation as it cools the area much like ice.

    The Nordic Lifting Elbow Support Sleeves provides excellent support but also because it is comfortable to wear. The sleeves do not bind or limit mobility, and they stay in place.
