Myositis (Muscle Inflammation)
Fibrosis is a process that follows chronic inflammation. Fibrotic tissue is like a scar tissue, thick, and rigid, due to excess accumulation of protein below the skin.
Scleroderma is named after skin fibrosis, which is one of its most common and recognizable symptoms. Skin fibrosis eventually develops in most patients.
Sclero means "hard" and derma means "skin". The diagnosis of skin fibrosis is clinical and it requires no laboratory or special testing.
Doctors may request skin biopsies when there are unusual patterns or areas of skin that become tight and firm. (Also see Types of Scleroderma)
IL-16 expression is increased in the skin and sera of patients with systemic sclerosis. The regional up-regulation of IL-16 in the skin is not only associated with skin sclerosis, but also with systemic IL-16 activation. PubMed, Rheumatology (Oxford), 08/03/2019. (Also see Interleukins)

High–frequency ultrasound (HFU) of the skin in systemic sclerosis (SSc): an exploratory study to examine correlation with disease activity and to define the minimally detectable difference. In the study, HFU was able to measure skin thickness, it correlated quantitatively with a valid measure of SSc activity, and a minimal detectable difference was identified.

An Ultrasound Surface Wave Technique (USWT) for Assessing Skin and Lung Diseases. USWE is a non-invasive and non-ionizing technique for measuring both skin and lung surface wave speed and may be useful for quantitative assessment of scleroderma and/or interstitial lung disease.

Self–assessment of skin tightness severity by scleroderma patients. The respective modified Rodnan skin score assessment by patient versus the physician was highly correlated with a high level of agreement. PubMed, Int J Rheum Dis, 04/29/2016.
The usual presentation is distal to proximal: finger tips first with progression to the fingers, hands, forearms, and arms. By the time the skin of the arms is tight, there may be stiffness of the legs, thighs, and in some cases, chest and abdomen. The pattern of skin stiffness is usually bilateral and symmetrical.
The skin of the face and neck may be involved in the mild, also called localized Scleroderma (with only finger tightness), or in proximal or diffuse Scleroderma (tight skin proximal to the hands).
Skin improvement is a surrogate for favourable changes in other organ systems in early diffuse cutaneous systemic sclerosis (dcSSc). Changes in lung function in early dcSSc closely parallel skin changes and modified Rodnan skin score improvement reflects better prognosis for visceral disease. PubMed, Rheumatology (Oxford), 11/27/2019.

At the first stages of skin tightening on the fingers, hands, and legs occupational and physical therapy are important in preventing, and ameliorating irreversible limiting contractures of the fingers.
Protection of the hand, and fingers by utilization of gloves when doing the dishes, gardening, and other physical activities prevents trauma that may break the skin, and produce slow healing ulcers with risk of infection.
A personalized physical therapy program or usual care for patients with systemic sclerosis (SSc): A randomized controlled trial. A personalized physical therapy program did not reduce disability at 12 months but had short–term benefits for patients with SSc. PubMed, Arthritis Care Res (Hoboken), 10/12/2016.
Oral hygiene may become difficult in cases where facial skin becomes tight. When the skin around the mouth becomes tight, it is called microstomia. You must make frequent appointments with your dentist, who should be aware of your disease and maintain communication with your doctor. (Also see Scleroderma Dental Involvement)
When the skin tightening progresses quickly, or involves the chest and abdomen, your doctor may choose among the medications currently used for this condition.
For UVA1 treatment, first contact your doctor to see if it they will recommend it for you. It is not used for lichen sclerosus that is on the genital area. If they recommend and prescribe it for you, try to find UVA1 facilities near you. Some dermatology offices (usually large offices or with major health centers) have UVA1 equipment (not UVB). It may also be possible to buy UVA1 phototherapy equipment for home use. It is manufactured by Daavlin and distributed worldwide. Home users must be monitored by a physician, who will prescribe the necessary dosage and monitor for possible side-effects, such as skin cancer.
Association of serum homocysteine level and lung involvement in systemic sclerosis (SSc). It seems that the serum level of homocystein has a minor role in the lung involvement of SSc patients or its effects are modified by other factors. PubMed, Curr Rheumatol Rev, 06/28/2018.

At present a similar study is being conducted to evaluate the role of Methotrexate. (1) (Also see Clinical Trial: Open Enrollments)
In addition, anecdotal reports of spontaneous remission are well known. Consequently, the initiation of specific therapy for this condition should be carefully evaluated and followed by your doctor. If started, all of these drugs require frequent laboratory monitoring for toxicity, and secondary effects. (1)
The skin tightening may occur rapidly, producing sudden increase in the pressure under the skin, and rubbing of the muscles and tendons below the skin. This may cause inflammatory muscle disease (Myositis), which frequently accompanies Scleroderma. In these cases, a blood test will show elevation of muscle enzymes.
Cessation of exercise, especially isotonic exercises that require repeated contraction of muscle groups, is mandatory. Isotonic exercises will increase the rubbing produced by the thickened skin, and augment the inflammation in the muscles. Your doctor may contemplate the use of steroids according to the degree of myositis. Repeated blood work for detection of muscles enzymes should be performed at your doctor's discretion.
