Help with Flexor Pollicis Longus Muscle Pain

Cold Therapy Gel For Flexor Muscles Hand Injury Pain

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relieve for new injuries and is great as a maintenance treatment for overuse and repetitive use injuries. Cold therapy should be used on new and recent injuries instead of heat as it cools the area much like ice and does not promote swelling. A recent study showed that Biofreeze decreased pain 2 times more than ice and the pain relief lasts 9 – 10 longer. Many who suffer from arthritis pain like to use Biofreeze on swollen painful joints. It is a favorite of athletes for both swelling reduction and pain relief due to injury and repetitive motion soreness.

Biofreeze is recommended for recent flexor pollicis longus muscle injury
Warm Therapy Gel For Flexor Pollicis Longus Muscle Pain and Stiffness
For arthritic or chronic hand pain relief I recommend Sombra Warm Therapy Pain Relieving Gel. Sombra provides warmth without burning and is better at relieving pain than other over the counter pain creams. To relieve flexor pollicis longus muscle pain apply Sombra all around the elbow and down the front of the forearm, into the wrist, hand, and thumb.
Sombra Warm Therapy Gel provides pain relief for sore arthritic hands.
Thumb Support For Pain Relief
If the pain in the thumb, especially around the thumb joint, is so unrelenting that you just need some relieve, I recommend that you try the Mueller Thumb Stabilizer. If your thumb pain is caused by the flexor pollicis longus muscle, bracing the thumb is not a cure, you must treat and support the muscle to eliminate the pain. However, there are times when the pain is unrelenting and bending the thumb is so painful you need help not only with the pain but also keeping the thumb stable. If that is the case this thumb brace will help. I like this particular brace because it provides support at the base of the thumb, and the joint in the thumb. The brace is lightweight, breathable, fully adjustable for compression and can be used for either hand. Highly recommended for those who use the thumb and first finger in a pinching type motion regularly. Keep it on hand (pun intended) for those times when you need support and pain relief.

Self Treatment For Flexor Pollicis Longus Thumb Pain

Do you know that small "knots" or other dysfunction in the flexor pollicis longus muscle can contribute to pain in the tip of the thumb that goes down into the joint? It can also make it difficult and painful to grasp an object or pinch with your forefinger and thumb.

If this pain pattern sounds familiar  I  recommend that you purchase Claire Davies  The Trigger Point Therapy Workbook: Your Self-Treatment Guide for Pain Relief. Mr. 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.  It takes time and practice to master finding trigger points, but once you learn you have a tool and method to help relieve muscle pain throughout the body.  If you have unresolved pain  in the thumb, it may be trigger points in the flexor pollicis longus muscles. Deactivating trigger points can reduce or eliminate this pain. This book is a must-have for anyone interested in finding the cause and treating muscle pain.

The Trigger Point Workbook can help you resolve muscle pain in your thumb, hand and wrist.
